1 51 Mar. 27, 1973 Primary Examiner-Kyle L. Howell Attorney-Jessup & Beecher [57] ABSTRACT An orientable electromagnetic catheter type flow meter and method are provided, which flow meter may be introduced, for example, into a blood vessel to measure the blood flow in the blood vessel, and which is constructed to have a minimal diameter so that it may be introduced percutaneously, for example, into a branch of a larger blood vessel with minimum damage. One embodiment of the flow meter of the invention to be described includes a thin resilient probe having an angulated end portion so as to place its pick-up electrodes adjacent the inner surface of the wall of the blood vessel diagonally or diametrically across the blood vessel from one another. The aforesaid flow meter in one embodiment is constructed so that its probe may be easily turned while in the blood vessel to different orientations with respect to an external magnetic field, in order first to establish a proper base line, and then to establish optimal orientation for flow sensing. In another embodiment the external field is turned, and in yet another embodiment the animal or human subject is turned together with the flow probe relative to the external magnetic field.
11 Claims, 11 Drawing Figures ORIENTABLE ELECTROMAGNETIC CATHETER PROBE AND METHOD BACKGROUND OF THE INVENTION nal Field Electromagnetic Catheter Flow Meter" filed Apr. 28, 1970 in the name of Alexander Kolin.
Electromagnetic flow meters include means for producing a magnetic field across the path of a moving fluid, so that a voltage may be generated as the fluid moves through the field. This voltage is directly proportional to the average velocity of the fluid. Electromagnetic flow meters are provided with a pair of pick-up electrodes disposed across a moving fluid stream and which are held in contact with the moving fluid, so that the voltage induced in the fluid may be measured, and the resulting voltage may be utilized to determine the velocity of the fluid.
The catheter type flow meter described in the aforesaid copending application includes a probe which may be straightened to a substantially linear configuration of minimal diameter, so that it may expeditiously be inserted into the blood vessel. The said probe is resilient, so that once it is inserted into the blood vessel, it may assume an S-shape or L-shape, or angular configuration, as described in the said copending application, and so that it may perform its flow meter function. The process of the present invention is also applicable to the loop-type of flow probe described in copending application Ser. No. 236,815 filed Mar. 22, 1972 in the name of Alexander Kolin.
Catheter type flow meters have been developed which comprise an electromagnetic flow transducer incorporated into a thin catheter-type tube, and which may be inserted into a branch blood vessel, such as the femoral artery or femoral vein, from which it may be maneuvered into a major artery, such as the aorta, or pulmonary artery; or vein, such as the vena cava. Such a flow meter is described, for example, by C. J. Mills, Phys. Med. Vol. 11, 323 (1966); and by Alexander Kolin et al, in the Proceedings National Academy of Sciences, 59, 808 (1968).
The electromagnetic flow meters described in the aforesaid copending applications include probes having the aforesaid resilient characteristics, and the probes are configured to assume the aforesaid S-shape, or loop-shape, or L-shape when in the blood vessel. The probes of the copending applications may be inserted percutaneously into the blood vessel by first straightening the probes into a linear configuration and by passing it through a tubular catheter into the blood vessel. The tubular catheter may be inserted into the blood vessel through a hollow needle in accordance with usual prior art practices. The probes described in the copending applications, therefore, may be introduced with a linear configuration into the blood vessel of the patient percutaneously, for example, through the tubular catheter, and the probes assume their angulated shape or loop shape after they emerge into the blood vessel under examination from the inner end of the catheter. The probes thus position their pick-up electrodes to the opposite sides of the blood stream within the blood vessel. While it is understood that the present invention can be used with either loop or L-type probes, and other similar configurations, the following description will be confined for simplicity to L-type probes serving as an illustration.
The preferred insertion technique is to introduce the resilient probe through the hollow catheter tube which, in turn, is passed through a hollow needle, the latter being used to puncture the skin and muscle. The hollow catheter tube terminates in the blood vessel at the point where the emerging probe is to measure the fluid flow. Then, as the probe emerges from the inner end of the tubular catheter within the blood vessel, its resilient characteristics cause it to angulate and to assume the desired configuration for proper flow meter operation. A sliding plug may be provided on the probe, and this plug is inserted into the external end of the tubular catheter and thereby prevents bleeding through the tubular catheter while the probe is being inserted into the blood vessel and during the flow measurement.
When the probe emerges from the inner end of the hollow catheter in the apparatus of the copending application Ser. No. 32,671, and as mentioned above, its resilient characteristics cause its pick-up electrodes to be displaced diagonally or diametrically across the blood vessel so as to perform their flow meter functions. A magnetic field is established within the blood vessel from an external means, such as an electric current carrying coil. Problems have been encountered with the aforesaid type of flow meter, in that it is necessary for the probe to be properly oriented within the blood vessel with respect to the lines of force of the magnetic field.
Specially, in order for proper measurements to be made, the probe is first oriented in accordance with the teaching of the present invention so that the plane defined by the stem of the probe and the end portion thereof which contains the electrodes is initially parallel to the lines of magnetic force developed by the external magnetic means. In such a position, the flow meter generates zero signal due to the fluid flow within the blood vessel, but the meter may develop a flow independent voltage related to eddy currents. This initial orientation permits a phase sensitive detector and compensator means to be adjusted so as to reduce extraneous current effects to zero, and thus establish the zero base line for the recording instrument. The aforesaid parallel orientation of the probe and electrode plane is evidenced when the pulsations in the output signal, corresponding to the pulsating blood flow in the blood vessel, are reduced to a minimum (ideally to zero).
After the zero base line has been established, the probe is then oriented in the practice of the invention so that the stern of the probe and the line joining the electrodes are preferably oriented to maximize their projection on the plane which is perpendicular to the direction of flow of the fluid. This is the condition for maximum sensitivity. This latter angular position is observable when the aforesaid recorded flow pulsations are maximized in the output of the instrument.
The aforesaid procedures may be carried out by turning the probe after it has been inserted into the blood vessel. It has been found that attempts to turn the aforesaid probe within the tubular catheter in which it is inserted into the blood vessel, especially when the catheter is bent or curved, creates a snap-action of the angulated internal end portion of the probe, so that difficulties have been encountered when it is attempted to turn the probe smoothly to a desired angular position with respect to the magnetic field. That is, it has been found that when the external protruding part of the probe is turned about its axis, there is no corresponding turning of the inner angulated part of the probe, until sufficient torque energy is built up internally due to the resilient characteristics of the probe, at which time the energy is released suddenly and actually snaps the inner angulated end portion of the probe through a large angle into an equilibrium position. This makes its very difficult to set the electrode plane to desired orientations, either parallel or perpendicular to the magnetic field.
The aforesaid difficulties are over come in the assembly of one embodiment of the present invention by providing a simple means for physically coupling the resilient probe to the tubular catheter, and by turning the catheter and the probe together. When that is accomplished, it has been found that as the probe and tubular catheter are turned about their common longitudinal axis, for example, the inner angulated end of the probe turns smoothly, so that it can be set to any desired angular position, without the aforesaid snap-action.
In another embodiment to be described, the relative orientations between the probe and the magnetic field are achieved by actually turning the magnetic field, either by physically turning the external magnetic field producing means, or by achieving the result electrically. In another embodiment, the patient together with the flow probe is turned to achieve the aforesaid relative orientations.

DETAILED DESCRIPTION OF THE ILLUSTRATED EMBODIMENT In the representation of FIG. 1, the electromagnetic flow meter of the invention is illustrated as inserted into a conduit, such as a blood vessel 10, for example, through a branch blood vessel 12. The flow meter includes a pair of electric leads or wires L, and L which are connected to a pair of electrodes E, and E The leads L, and L may be resilient steel wires, for example, insulated by Teflon or other suitable insulating material. The electrodes E, and [3,, as described in the aforesaid copending application Ser. No. 32,671, may have any suitable form.
For example, the electrodes E, and E may be the ends of the wires L, and L formed into appropriate coils; or they may be metallic strips, or formed of metallic paste, or any other desired configuration. The preferred construction utilizes insulated (preferably Teflon) wires of steel, or other resilient metal, which are either twisted or coaxial to provide a stiff resilient noninductive stem for the probe. One of the wires L, is broken off and insulated near electrode E, while the other wire L continues somewhat beyond electrode E The aforesaid resilient probe, as described in the copending application Ser. No. 32,671, may be formed by the leads L and L, themselves. These leads, for example, may be Teflon insulated resilient steel wires twisted and bonded together; or they may be insulated flexible wires, twisted around a resilient steel stem or spine. The lead L, is made somewhat shorter than the lead L and the insulation is removed from its righthand end, and that end is coated with a conductive metal paste which hardens to form an electrode E,. Alternately, a tine wire, preferably platinum, may be soldered or otherwise conductively fastened to the base end of the lead L, and coiled around the stem to form the electrode E,, as shown in FIGS. 1 and 1a. The electrode E, is insulated from the lead L, by virtue of the insulation on the latter lead. The bare end of the lead L, may also be coated with a conductive metal paste to from the electrode E or it may be soldered or otherwise conductively connected to a thin wire, for instance platinum, which is coiled around the end of L,, as also shown in FIGS. 1 and la, to form the electrode E,. The loose ends of the wires forming the electrodes E, and E, are fastened to the stem by epoxy or another suitable cement.
Protection against scratching of the inner wall of the blood vessel 10 as the probe is manipulated within the blood vessel is provided, for example, by forming a loop 18 at the end of the probe. A bead 21 of silicone rubber, epoxy or other material which hardens into a smooth non-liquid drop from a liquid state, may be placed within and around the loop 18 to envelop the loop and to create a smooth dull end which will not injure the artery wall when rotated or otherwise moved against it.
The leads L, and L, are preformed so that when they are inserted into the blood vessel, and when their ends emerge from the hollow catheter C, they assume the angulated configuration shown in FIGS. 1 and 10. Moreover, the leads may be straightened to a linear configuration as they are inserted into the hollow catheter C. As mentioned above, the leads L, and L, may be twisted or parallel to one another. As an alternative, the leads may be contained in a hollow resilient sheath, which then forms the resilient stem of the probe. As another alternative, the leads themselves may be soft and flexible, and a third thin resilient wire may extend longitudinally between them or next to them and be bonded to them so as to form the desired resilient stern of the probe.
A magnetic field may be created in the blood vessel in a space encompassing the electrodes E, and E by means, for example, of an electric current carrying external coil 16, such as shown in FIG. 2. The external coil 16 may have any appropriate configuration to create the desired magnetic field in the blood vessel 10, and it may be positioned, for example, around, under or over the patient. The external coil 16 may be flat and lie directly on the surface supporting the patient, or it may be shaped, for example, as described in the copending application Ser. No. 873,240, as a cradle.
The latter configuration of the coil is shown in FIG. 2. For that configuration, the patient lies directly within the coil as shown in FIG. 3. Smaller coils may be made, and they also may have a cradle-like configuration, so that the arm or leg of the patient may be placed into the coil, when measurements are to be made on blood vessels within the arm or leg. The coil 16 may also be a flat annular coil or have any other suitable configuration, and as mentioned above, the patient may be above, beside or below the coil. Alternately, two or more coils may be used, and the patient may be sandwiched between them, or any other means for establishing a magnetic field within the blood vessel 10 may be used.
The coil 16 may have any desired number of turns, so as to produce the desired magnetic field across the blood vessel 10, as shown in FIG. 4. In FIG. 4, the blood vessel 10 is shown on an enlarged scale as a transverse section. An alternating current is introduced into the coil 16, and the coil thereby generates an alternating magnetic field having a component in the illustrated direction in FIG. 4, symbolized by the vector B across the blood vessel 10, so that the fluid flowing through the blood vessel flows transversely through the magnetic field and develops an alternating current voltage which is picked up by the electrodes E, and E The electrodes E, and E, are preferably platinized platinum, or otherwise treated, so as to exhibit non-polarizing characteristics so as to eliminate polarization of the electrodes which adversely affects the proper electrical operation of the instrument.
As mentioned above, the electrodes E, and 13,, in the position shown in FIG. 4, are in position to generate maximum electrical signals corresponding tothe blood flow through the vessel. However, as an initial adjustment, and in order to establish the zero base line, the electrodes must first be turned so that they lie in a plane parallel to the magnetic lines of force, that is, they must be turned through with respect to the representation of FIG. 4. The construction of the present invention is such, as will be described, so that the end of the probe on which the electrodes are mounted may be easily and smoothly turned so as to establish the desired orientations within the blood vessel. Or the magnetic field can be rotated so as to achieve the same orientation relative to the electrodes.
The system of FIG. 3 shows the manner in which the external coil 16 may be energized from an appropriate alternating current source 50. The coil leads W, and W, are connected to the source 50, so that an alternating magnetic field may be produced within the blood vessel, such as the aorta of the patient. The leads L, and L, from the pick-up electrodes E, and E supply the resulting alternating current signals to an appropriate detector and amplifier 52., and the amplified output signal from the amplifier 52 is applied, for example, to a recorder 54 so that a record may be made.
The alternating current source 50, as well as the detector and amplifier S2 and recorder 54, are well known electrical units and are available commercially. Therefore, it is believed unnecessary to illustrate or discuss such units in detail herein. It might be pointed out that the detector 52, as is well known to the art, is a phase sensitive detector, and does not respond to quadrature phase signals which are produced by eddy currents, and which are not a function of the blood flow. It will be appreciated that the orientation concepts described herein are equally applicable to the loop probes described in the aforesaid copending application Ser. No. 873,240.
In the operation of the apparatus of the invention, the resilient probe formed by the leads L, and L is initially straightened and inserted into the catheter C with a linear configuration. The catheter is then inserted into the blood vessel 10, for example, by usual prior art percutaneous methods, as described above. During the insertion process, a plug 17, which is slidable on the leads L, and L is inserted into the external end of the tubular catheter C, so as to prevent bleeding through the tubular catheter C. The plug 17 may also have the form of a conical perforated member which is slidably mounted on the leads L,, L so that it may be moved along the stem of the probe. The plug 17 serves to close the end of the catheter C as the probe is introduced into the catheter, and the probe is then pushed through the plug into the catheter C until its inner angulated end emerges in the blood vessel from the end of the catheter, such as shown in FIGS. 1 and 1a. In this way, no significant amount of blood can escape through the tubular catheter C as it is being inserted and after it has been inserted into the artery or vein. The plug may, for example, be formed by winding a Teflon tape around the probe in a conical configuration, or it can be made of two halves of a Teflon member with a groove in each half to accommodate a probe. Clearly, the plug 17 may be formed in any other appropriate manner, and of any appropriate material suitable to perform its intended purpose.
As explained above, when the probe L,, L, has been inserted into the blood vessel, such as shown in FIGS. 1 and la it must first be oriented to a position such that the plane of its electrodes E, and IE. lies parallel to the lines of force from the external magnetic field, in order that the zero base line may be established. However, in trying to rotate the probe inside a bent artery or inside a bent catheter tube, such as the tube C, for that purpose, it was found that the probe does not rotate smoothly at its angulated or looped end. Instead, and as mentioned above, the angulated end portion of the probe turns suddenly to a new equilibrium position as the probe is turned about its longitudinal axis, without stopping at intermediate angles. This action prevents the shaped end of the probe from being set easily to desired different angular positions for the aforesaid purpose, insofar as the flow meters described in the copending applications are concerned.
To remedy the unwanted snap-action of the shaped end, the assembly of the present invention provides a simple means for mechanically coupling the probe to the tubular catheter C, and this means comprises in the illustrated embodiments of FIGS. 1 and la, the formation of a V-shaped slot or notch 19 at the inner end of the hollow catheter C. Then, in order to insert the probe into the blood vessel, the probe is straightened and inserted through the tubular catheter C, as described above, until its angulated end protrudes from the inner end of the catheter C and assumes its angulated shape, shown in FIGS. 1 and la The probe is then drawn back into the hollow tubular catheter C, with a gentle withdrawing action until it falls into the slot 19, as shown in FIGS. 1 and 1a, and is thereby effectively coupled to the catheter C. As shown in FIG. la, it is advisable to cut the inside end of the catheter C at a slant and to locate the V-groove opposite the tip of the cut end to facilitate slipping of the probe bend irito the V-groove when the stem is pulled. It is preferable to locate the electrode E directly adjacent the bend in the probe, so that the electrode E will be directly adjacent the end of the tubular catheter C, and will have a section lying outside the catheter in the blood stream as the probe is entrapped within the slot 19. Two such grooves diametrically opposite one another may be used in the loop type probe described in the copending application Ser. No. 873,240.
Then, in order to turn the angulated end of the probe to any desired angular position, the catheter C and the probe are turned together, for example, by means of a handle I-[ shown in FIG. 3, although such a handle is not essential since the catheter C itself may be grasped and twisted to perform the desired orientation operations. This turning of the probe and the hollow catheter together provides a smooth turning action within the blood vessel, insofar as the angulated end portion of the probe is concerned, and a simple solution to a very difficult problem. The resulting assembly is easily capable of being set to any desired angular position of the inner end portion of the probe within the blood vessel. The looped end 18 of the probe, as mentioned above, prevents scratching or otherwise injuring the inner wall of the blood vessel while the aforesaid manipulation is being carried out. Preferably the probe may be withdrawn partly into the catheter tube during rotation so that the probe end does not scrape the artery.
Therefore, by the provision of the V-groove 19 in the end of the catheter C, and by causing the bent end portion of the probe to engage the V-groove, as the outer catheter C is rotated, the bent end of the catheter probe rotates with it, and it may be stopped at any desired angle.
In the modified construction of FIGS. 6 and 7, a metallic hypodermic tube is used in place of the wire L of the prior embodiment. The tube 100 has an outer insulation layer. In the embodiment of FIG. 6, the insulation is scraped from the end of the tube 100 to form the electrode E The resulting bare surface is preferably gold plated and then platinized. Alternately, a thin platinum or silver wire may be soldered to the tube and wound around it and then platinized to form the electrode E or a thin platinum wire soldered to the tip of tube 100 is wound on the insulated wire L to form electrode E as shown in FIG. 7.
In both the embodiments of FIGS. 6 and 7, the wire L is inserted into the tube 100 and liquid epoxy 101 is introduced into the tube. After the probe is in position, the epoxy 101 is allowed to harden to bond the probe to the tube. As shown in FIG. 8, the portion of the probe between the electrodes E and E may be thickened with a non-conductive tube or layer 102.
Therefore, in the embodiment of the invention described above, the zero base line is established by keeping the direction of the magnetic field constant, and by then rotating the probe about the long axis of its stem so that the orientation of the plane of the bend of the probe varies relative to the direction of the magnetic field. In a second embodiment, the probe may be left within the blood vessel in orientation in which it comes to rest after its introduction, and the orientation of the magnetic field with respect to the probe may be altered so as to achieve the same results.
The foregoing may be achieved in more than one way. For example, one way of achieving the result would be to mount the coil generating the magnetic field, such as the coil 16 of FIG. 2, in such a fashion that it could be revolved around an axis which is approximately coaxial with the stem of the probe, or with the axis of the blood vessel. Alternately, the patient in FIG. 3 may be turned about such an axis while holding the coil 16 stationary. In either case, the direction of the magnetic field contributed by the straight portions of coil 16 at the center of the rectangle defined by these straight portions is perpendicular to the plane in which said straight portions lie and the magnetic field will be perpendicular to the axis of rotation if the latter lies in the plane defined by the straight portions of coil 16. The objective of rotating either the patient or the coil 16 is to change the angle between the magnetic field of coil 16 and the plane of the bend of the probe which can be for a half revolution of the coil or the patient. When the coil is oriented so that the plane defined by the straight portions of the coil 16 is parallel to the plane of the bend of the probe, a maximum flow signal is obtained. However, when these two planes are mutually perpendicular so that the magnetic field is parallel to the plane of the bend of the probe, the flow signal is precisely zero.
As in'the previous embodiment, the orientation in which the magnetic field is parallel to the plane of the bend of the probe, and in which the flow signal is zero, is utilized for adjustment of the phase sensitive detector to obtain a zero signal. In other words, the phase of the phase sensitive detector is adjusted for zero signal, and so the recorder does not alter its reading when the magnetic field is turned on or off. Now, having adjusted the phase sensitive detector for the zero signal reading, the magnetic field is turned through 90 by turning the coil 16 into an orientation in which the optimum flow signal is obtained. The system is now adjusted so that the flow signal which is being recorded is being recorded relative to the correct base line, namely, the line which gives a zero reading for the zero flow. And the same base-line is obtained when the flow is stopped as is provided when the magnetic field is turned off without stopping the flow.
Instead of mounting the coil 16 of FIG. 2 on an appropriate bracket for rotation, as described above, the coil may merely be placed in a first position for zero reading adjustment, and a second position perpendicular to the first position for normal flow signal recording. Practically this can be done as follows: The normal position for the coil 16, for example, could by lying flat under the subject which is located on a slightly elevated board. This is the position for optimum blood flow recording. Now, the position for zero signal would simply by one in which the coil is pulled out from under the subject and placed on the side of the subject the coil standing on its edge. In the latter case, a zero flow signal is derived, and it is in the latter position in which the phase sensitive recorder is adjusted to give the zero signal.
A third way of accomplishing the desired result would be to have two coils, designated 16A and 168 in FIG. 9 and positioned at right angles to one another. The coil 16A, for example, may be positioned under the subject, and the coil 168 on the side of the subject. The coils may be oriented in such a fashion that the magnetic fields generated by the two coils are perpendicular to each other. The two coils may now be used as follows: First, excite, for example, the vertical coil 16A and orient its magnetic field with respect to the probe by shifting the probe or the coil slightly so that a zero flow signal is obtained, the zero flow signal being recognized as in the previous embodiments by the disappearance of signal pulsations due to the arterial blood flow. The phase sensitive detector is now adjusted so that the recorder reads zero. Having achieved this, the vertical coil 16A, which is on the side of the subject is de-energized, and the horizontal coil [68 which is under the subject is energized. The magnetic field of the coil 16B is perpendicular to the field of the coil 16A, and the flow signal is now optimally sensed. That is, there is now optimum orientation of the magnetic field relative to the probe, and the base line is calibrated to be zero for zero flow.
A resultant magnetic field of any desired orientation with respect to the probe may be achieved by exciting both coils 16A and 16B simultaneously in series or in parallel. Then, the magnetic field is the resultant field which is obtained by vectorial addition of the two individual field components B A and B shown in FIG. 9. For example, if there two fields are of equal magnitude, then the magnetic field, the resultant field, is going to be inclined at 45 with respect to either of these two fields. If the intensity of, for example, the horizontal magnetic field is now diminished, the horizontal component of the resultant field becomes smaller and 6 smaller and finally when the horizontal component becomes zero, a purely vertical magnetic field then exists. Conversely, if the horizontal component is held constant and the component of the vertical field is diminished, then the magnetic field which started out as a 45 field relative to the horizontal becomes closer 5 and closer to the horizontal, and when the vertical component disappears a purely horizontal magnetic field results.
It is thus possible, and this is a very convenient fea ture of this implementation, to rotate the direction of the magnetic field without physically rotating any apparatus and in this fashion the orientation of the magnetic field relative to the plane of the bend of the probe can be controlled so as to make the adjustment as previously described. This simply means that the intensity of at least one of the two magnetic fields is changed until the pulsating signal due to flow disappears. The phase sensitive detector is then adjusted to provide a zero reading, and then the direction of the resultant magnetic field is rotated by 90 simply by exchanging the value of the current in the two coils. In the latter operation of exchanging the currents of the two coils it is important to make sure that the relative phase with the two currents with respect to each other remains preserved. That is, if, for example, the currents in the two coils are in a phase aiding relationship when superimposed, they must remain in a phase aiding relationship after the switching operation.
As shown in FIG. 10, if desired, the patient may be supported on a rotatable table 120 over the coil 16, and the coil may be flat on a further stationary support surface, such as a table top. Now the desired results of the invention may be achieved by turning the table 120 and the patient until the desired relative orientations, as discussed above, are realized.
Insofar as the probes of FIGS. 6 and 7 are concerned, for example, an additional line such as a fishing line-' 109 may extend through the tube 100 to the end of the protruding wire L This latter line may be pulled back, after the catheter is in place so as to establish the probe at any desired angulation up to, for example, 90.

Great product!
I bought Wormwood Black Walnut by Gaia Herbs, but realized I might not want to use it because with candida, you are not supposed to have alcohol. I guess I didn't read the label well before purchasing. I think all tinctures have to have alcohol though. Wormwood and black walnut are good anti parasitics and I believe Gaia to be an excellent product.
Great combo for anti parasitic purposes.
Contains alcohol.
√ I would recommend this item to a friend.

AIDA64 Disk Benchmark
Many enthusiasts are familiar with the Finalwire AIDA64 benchmark suite (formerly Lavalys EVEREST), but very few are aware of the Disk Benchmark tool available inside the program. The AIDA64 Disk Benchmark performs linear read and write bandwidth tests on each drive, and can be configured to use file chunk sizes up to 1MB (which speeds up testing and minimizes jitter in the waveform). Because of the full sector-by-sector nature of linear testing, Benchmark Reviews endorses this method for testing SSD products, as detailed in our Solid State Drive Benchmark Performance Testing article. However, Hard Disk Drive products suffer a lower average bandwidth as the capacity draws linear read/write speed down into the inner-portion of the disk platter. AIDA64 Disk Benchmark does not require a partition to be present for testing, so all of our benchmarks are completed prior to drive formatting.
Linear disk benchmarks are superior bandwidth speed tools in my opinion, because they scan from the first physical sector to the last. A side affect of many linear write-performance test tools is that the data is erased as it writes to every sector on the drive. Normally this isn't an issue, but it has been shown that partition table alignment will occasionally play a role in overall SSD performance (HDDs don't suffer this problem).
The high-performance storage products tested with Lavalys AIDA64 Disk Benchmark are connected to the Intel P67-Express SATA 6Gb/s controller and use a 1MB block size option. Charted above, read performance on the 256GB Samsung SSD 850 PRO solid state drive measured average speeds of 507.7 MB/s. As seen from the consistent flat-line wave form, the average read speed was virtually identical to this drives maximum peak speeds of 507.9 MB/s across the full range of capacity. AIDA64 linear write-to tests were next…
The waveform chart above illustrates how well the Samsung SSD 850 PRO manages file transfers, indicating linear write performance speeds that appear uninterrupted. The 256GB Samsung SSD 850 PRO solid state drive recorded an average linear write-to speed of 479.3 MB/s, with maximum performance reaching 484.0 MB/s.
AIDA64 combined benchmark speed performance results for the Samsung SSD 850 PRO surpassed every other SATA-based SSD we've tested, firmly outperforming the Intel SSD 520 series.
The chart below shows the average linear read and write bandwidth speeds for a cross-section of storage devices tested with EVEREST:
Linear tests are an important tool for comparing bandwidth speed between storage products – although HDD products suffer performance degradation over the span of their areal storage capacity. Linear bandwidth certainly benefits the Solid State Drive, since there's very little fluctuation in transfer speed. This is because Hard Disk Drive products decline in performance as the spindle reaches the inner-most sectors on the magnetic platter, away from the fast outer edge.
In the next section we use PCMark Vantage to test real-world performance…

Congratulations to the NFC Championship Arizona Cardinals!
They were the dark horse of the NFL 2008-2009 playoffs. I wanted them to win because I didn't like anyone else, and because I like seeing history in the making. I hoped they would but didn't think they'd beat Atlanta, where they came away with a 30-24 victory after shutting down the Falcon's running game. I hoped they would but didn't think they'd beat Carolina, who they destroyed 33-13 and dominated every facet of that game. Finally, I hoped and couldn't have dreamed they could beat Philadelphia, who they shut down in the first half and the final quarter for a 32-25 victory over the Eagles. I believe this is the first Superbowl in franchise history the Cardinals will play in.
Stunned. I'm happily stunned. Arizona fans should be damn proud of their team.
Anybody but Philly......Congratulations Cardinals
"To believe that social reforms can eradicate evil altogether is to forget that evil is a protean creature, forever assuming a new shape when deprived of an old one." - SAT
Never argue with an idiot - they'll bring you down to their level then beat you with experience.
I'm happy for the cinderella team as well...although Bal or Pitt are going to be tuff tuff tuff...
Just be glad you aren't a football fan in Detroit
They did sign a new QB, his last name is Owen and he'll be wearing the number 16.
I'm happy for the red birds, didn't think I'd see them in the big dance in my life time.
While people are saying "Peace and safety," destruction will come on them suddenly, ... and they will not escape. 1Th 5:3
Way to go Cardinals!!!!!

and the sunshine patriot will, in this crisis, shrink from the
service of his country; but he that stands it now, deserves the
love and thanks of man and woman."
-- Thomas Paine (The American Crisis, No. 1, 19 December 1776)
The world is truley out of sink!!!
Go Cards!!
Were going to the Super Bowl, Go Cards !!!!
P.S. At least we gave the Losing Fans beautiful Arizona Weather instead of their frigid cold.
"When the people fear the government you have tyranny...when the government fears the people you have liberty."
--Thomas Jefferson --
It's going to be a Cardinals - Steelers Superbowl. I'm honestly glad, because I think the Steelers are the strongest team in the Playoffs and most deserving to be there, and the Cardinals are proving that they're ever bit the contender nobody gave them credit for being. Roethlisberger, play well, but I'll be rooting for the Cards this year.
I have been a Steelers fan for a long time. But being that I found out today that Arizona has a real footbal team. I am a bit confused.......
Go Steelers!! I mean Cards............
Go Cards! I couldn't stand it if the Steelers won. I was rooting against both teams for the AFC hoping somehow they would both lose.
That said, that hit in the 4th was pretty scary.
There are two sides to every issue: one side is right and the other is wrong, but the middle is always evil.
Who is John Galt?
Hope the Cards take it all! There've definitely been some unexpected winners in the playoffs (or, as the Dallas Cowboys refer to it -- vacation).

Greenmantle HTML version
14. The Lady of the Mantilla
Since that first night I had never clapped eyes on Sandy. He had gone clean out of the
world, and Blenkiron and I waited anxiously for a word of news. Our own business was
in good trim, for we were presently going east towards Mesopotamia, but unless we
learned more about Greenmantle our journey would be a grotesque failure. And learn
about Greenmantle we could not, for nobody by word or deed suggested his existence,
and it was impossible of course for us to ask questions. Our only hope was Sandy, for
what we wanted to know was the prophet's whereabouts and his plans. I suggested to
Blenkiron that we might do more to cultivate Frau von Einem, but he shut his jaw like a
'There's nothing doing for us in that quarter,' he said. 'That's the most dangerous
woman on earth; and if she got any kind of notion that we were wise about her pet
schemes I reckon you and I would very soon be in the Bosporus.'
This was all very well; but what was going to happen if the two of us were bundled off to
Baghdad with instructions to wash away the British? Our time was getting pretty short,
and I doubted if we could spin out more than three days more in Constantinople. I felt
just as I had felt with Stumm that last night when I was about to be packed off to Cairo
and saw no way of avoiding it. Even Blenkiron was getting anxious. He played Patience
incessantly, and was disinclined to talk. I tried to find out something from the servants,
but they either knew nothing or wouldn't speak - the former, I think. I kept my eyes
lifting, too, as I walked about the streets, but there was no sign anywhere of the skin
coats or the weird stringed instruments. The whole Company of the Rosy Hours
seemed to have melted into the air, and I began to wonder if they had ever existed.
Anxiety made me restless, and restlessness made me want exercise. It was no good
walking about the city. The weather had become foul again, and I was sick of the smells
and the squalor and the flea- bitten crowds. So Blenkiron and I got horses, Turkish
cavalry mounts with heads like trees, and went out through the suburbs into the open
It was a grey drizzling afternoon, with the beginnings of a sea fog which hid the Asiatic
shores of the straits. It wasn't easy to find open ground for a gallop, for there were
endless small patches of cultivation and the gardens of country houses. We kept on the
high land above the sea, and when we reached a bit of downland came on squads of
Turkish soldiers digging trenches. Whenever we let the horses go we had to pull up
sharp for a digging party or a stretch of barbed wire. Coils of the beastly thing were lying
loose everywhere, and Blenkiron nearly took a nasty toss over one. Then we were
always being stopped by sentries and having to show our passes. Still the ride did us
good and shook up our livers, and by the time we turned for home I was feeling more
like a white man.

This pudding can be made using bread or croissants. Slices of fruit bread would also be good. You could make one big dish or individual serves. This recipe makes enough to serve 4.
1 Heat the oven to medium.
2 Butter the inside of an ovenproof serving dish.
3 Rip, cube or slice about 500g of the bread you are using and pack this into the buttered dish.
4 In a solid pan mix together:
1½ cups of milk and ½ cup of cream
3 tbs castor sugar
a pinch each of ground nutmeg, cinnamon and salt
Half a vanilla pod (split) or 1 teaspoon of pure vanilla essence
If using a vanilla pod, heat this now until the sugar is dissolved then cover the pan and allow the pod to infuse for a while.
If using vanilla extract, heat the other ingredients and add the extract once you remove them from the heat.
5 In a large bowl whisk 3 medium eggs and 2 yolks. Pour half the hot milk mixture into this while you keep whisking, then gradually whisk in the rest.
6 Pour this over the bread in the ovenproof dish. Cover with cling film and leave for half an hour so the bread soaks up all the custard.
7 Set a baking tray half filled with water on to the middle tray of the oven.
8 Remove the plastic from the pudding and sprinkle the top with some raisins, sugar and a pinch of cinnamon and grated nutmeg. Dot with butter.
9 Sit pudding in the water bath. The water should be about halfway up the side of the dish. Top up if required. Cook for a good 40 minutes. A skewer should come out clean when the pudding is cooked.
Serve with cream, either liquid or whipped.
Hot buttered rum
Makes 6 drinks
1 In a bowl, mash together a third of a cup of packed dark brown sugar, 4 tablespoons of unsalted butter, half a teaspoon of pure vanilla extract, and a good pinch each of cinnamon, ground cloves, ground allspice and freshly grated nutmeg. This must be well combined and can be kept for a couple of weeks. Before using, bring to room temperature.
2 Warm the mugs and glasses you are using with hot water. Empty these and fill the warm mugs with a ¼ cup of dark rum and ½cup of boiling water.
3 Stir in a generous tablespoon of the spiced butter, top with whipped cream and a final grating of fresh nutmeg.

Looking for feedback
Any feed back for this design would be apprechiated.
Any feed back for this design would be apprechiated.
Sense its a simple design try making several variations. You may wont to try drawing it traditionally and scanning it in and adding value. Once you have several you will have a better idea what is working and what is not sometimes you need something to compare the work to. You know these kind of look like sculls what if you put teethe at the bottom? Good luck
i think that you need to work out the concept too. maybe if you put them in a different situation would be better. Try to find the funny side I would change the drawing style and use more straight lines, and if you hide the lines of the vectors would be great too. Good luck with your design :)
it look unfinished.. i would clean up the lines, add details and add some highlights or shading or maybe textures.. it looks flat to me right now.. and most important thing is the concept...
family theme?

The police officer charged with organising drug runs for a methamphetamine ring and accessing the police computer system to tip off his colleagues in the Head Hunters gang has been granted bail.
Father of five, Peter Pakau, faces 27 charges relating to methamphetamine, in addition to allegedly accessing the computer system and supplying information to gang members.
The 36-year-old's case was called at the Waitakere District Court today where he was granted bail by Judge Brian Callaghan.
He is on 24-hour curfew at his Henderson home and has been ordered not to associate with his co-accused.
His wife, Diane Pakau, a Waikato health worker, and seven others - including Shane Boag, Paul Holloway and Melissa Brown - have also been arrested in relation to the alleged enterprise.
Pakau is allegedly part of the enterprise, which manufactured and distributed methamphetamine.
He was linked to two methamphetamine cooks whom he organised to manufacture the drug, which he would then take in "substantial amounts'' to his dealer or supplier, according to the summary of facts.
"His role was significant because he was accessing the police computer system,'' said Crown prosecutor Brett Tantrum at the officer's first court appearance.
The information was allegedly used to advise Pakau's associates, who included members of the Head Hunters gang.
The drugs charges carry a maximum penalty of life imprisonment.
Pakau is also charged with conspiring to defeat the course of justice on three occasions and theft of a vehicle, and Mr Tantrum said further charges against him were likely.
A police investigation involved tracking devices on Pakau's car, and evidence included details of him accessing the computer system and intercepted communications he took part in, the court heard.
Pakau graduated from Police College in 2008, winning a section achievement award for his contribution to the success of his wing. He was posted to Henderson.
A year later, he was acknowledged for rescuing a woman who was being assaulted during a domestic incident in Waitakere when he reportedly tackled her offender to the ground.

This is a very nice park with nice views of lawns, trees, water, etc. Plenty of walking areas. Unfortunately the RV spots are all stone/crushed gravel - no grass by the sites, but level and clean. Helpful attendant helped us park. Sites themselves are close together, but certainly not on top of each other. Situated in Sycamore, IL - a nice town for walking or bike riding. We stayed here so that we could drive in and ride the Fox River Bike Trail - 20 minutes east of here. We would stay here again. - Deb and Chris

Very well maintained park. Nicely defined grass/gravel areas.
No tents, screen rooms with bottoms, or rugs allowed on the grass. This keeps GRASS there, not weeds.
I do not agree with paying for visitors, but there is a $2/visitor fee.
Grass sites are limited, and as all sites are, tight. Parking your tow vehicle is in convenient.
One of the most well maintained parks I have been to.
A lot of comments on the owners. I have had no problems. Follow the easy and common sense rules, you shouldn't have any problems. Owners are particular and strict, but the outcome is a nicely maintained park.
Spacing good but DEPTH LACKING.
Owner guides you to site, no problems even with 42' 5er. - Magiccowinuse

If there was nothing else its location would make it worthwhile.
This park features two small lakes, about a mile and a half around the two. Small boats are OK, fishing is catch and release. There is a big sandy beach on one lake with a buoy roped swim area. Also paddle-boats.
The owners have resisted putting camp sites around the lakes, most would have, the walks around the lakes are clear and improved and very pretty, with picnic tables, and flowers.
All the RV areas are level gravel with easy hookup to very convenient pedestals. All sites are back-in, end-to-end, but because the sites alternate, like a checker board, everyone has there own area. Each site has some shade, a picnic table, and fire ring.
The lack of grass at the individual sites is more than covered by the acres of beautiful green lawns. Always mowed and ready for a barefoot walk, because everyone picks up after their dog. The park is too beautiful not to!
The flowers and shrubbery are very professional. All of this is kept clean, neat, and groomed every day.
There is no cable because Rockford and Chicago are very near. The Wi-Fi is by TengoInternet and free. Wi-Fi can slow down if the park is busy.
The bathrooms and showers are all-in-one style and very clean and comfortable.
The laundry seems pricey but note that the machines are front-loading commercial washers and dryers; fill them to the limits indicated. They do a good job.
The owners have their home here at the park. It is a lovely home and all the park and campers spread out before them. We are camping on their front yard.
The owners are very proud of the park and work hard every day to keep their home clean and neat. To this end,there are rules. These rules ensure a clean, safe, and secure campground. All rules are printed on the welcoming brochure and there are none that I have not seen at other parks.
This is like an oasis, with all the large, old trees surrounding the property you wouldn't know a city was nearby. - Jack B

Park is primarily seasonal campers. Transient sites are far from the showers/restrooms.
Cable hookup at our site did not work. When informed of the problem, manager's reply was "it should, its just a cable". Our companion travelers at another nearby site also could not get cable. Fortunately, there are a number of OTA channels available.
Laundry was adequate and reasonable.
WIFI seemed to work OK when used for email and short web surfing periods.
The park is nice looking, pricey, and certainly adequate as an overnight stay. - Lakewood90

This looks like a local community weekend campground, with one section around the canals and large lake, all have permeant RV's. This is gated off. But you still can walk through and enjoy the lake. It seems like there were many used on weekends and special holidays. But there there several that look like they stay there for long term. But this is not the section that short term travels use. They have a separate section for the short term visitors. It is in the front of the park. They have really nice long pullthroughs. We got a site with electric and water only. We were just on overnighter. I would stay here again. - Honeybear & Sugarbear

I think the park's primary focus it seasonal but we did have an OK site. Truth be told, I would not have wanted the seasonal sites as they were right next to I-90 with very loud traffic noise. Where our site was, you could hear it but not that bad, just a constant back ground noise. I would stay here again if in the area. - Jack&Wanda

What a beautiful campground. It is very large and evenly split between RV and Campers. The campers are mostly up front where you enter the park. They have an extremely large area for campers. There are some tight fitting RV sites with full hook ups. Large dog park, bathrooms and laundry facility. Our site was right on a hill so leveling our RV was difficult. The park offers, Mini Golf, Frisbee Golf, and several other games. My biggest complaints were the flies and mosquitoes. The weather was perfect when we were there in August and the local town offered some great family owned restaurants. - Okstatefanz

The grounds were so pretty. Hardest working people you'll ever see. Level, gravel sites. We stayed 3 nights. Not much choice of campgrounds in the Chicago area. We don't stay at KOA's much because they are a little pricy, but this is a great place to bring your kids. Nicest tent area I've seen - grassy and shaded. - Jim & Patsy
Aug 2016 - $49.00
As a retired couple we normally don't stall at KOAs, as they are more kid/family oriented and have amenities (pools, playground, etc.) that we don't use. But we stayed here 4 days while meeting up with relatives travelling cross-county, and they picked it for being closest to Chicago with full-hookups (and decent ratings). We are glad we did. The campground is clean, well-maintained, with a fairly new and clean shower-house (in the RV section, we did not try the one in the tent-camping area). Campsites are gravel/dirt and fairly level, all are grass-separated with picnic table and fire-rings. There are about 25 full-hookups, and some are tree-shaded. Entrance requires a key-card, and they charge for visitors. The pool looked clean (didn't use it) and they have a 9-hole, par 2 miniature golf course. No cable TV available, but lots of Chicago/Rockford stations available.
The only downside I saw was the front entrance drive (about 100 yards long) is a single lane with a 90 degree curve at the office. On the slight chance you meet someone coming the other way, it will be an issue if you can't back up. And in the last hour before checkout deadline, the road can get crowded with people stopping at the office to check out. - Jim n Lynn

If you are traveling through like us, this is a great option. The staff are super friendly and helpful. The park is huge and they have a very nice, large pool. It's a nice park... however.
You are not at a campground, you are more like in a neighborhood of trailers 5th wheels. This is not a reflection on the staff or the park. Unfortunately thousand trails is trying to sell, sell, sell spots. I get it but it changes the feel of the place. It's too bad because the park is well laid out. We walked the park and the park is FULL but no one is here. We got one of the last spots remaining for the night and we were here mid week. I will say one of the downers was when I was cooking dinner I went inside and when I came back out there was a cat on my picnic table checking out what I was cooking. Like I said, it's a neighborhood. Nice park, nice people, but not really a campground. - scruggsfamilyRV

The site was very level with plenty of room, utilities worked just fine, roads are gravel but in good shape, pool was nice and warm, showers were some of the nicest we've seen. The WiFi and the Verizon signal weren't great at the site, but WiFi worked great in the clubhouse and within 50-100 ft of the clubhouse. Everything was pretty clean and well cared for. Road noise from the tollway was noticeable but not a burden. - Living Our Dash

The rate reflects Thousand Trails Membership. They only have 30 amp service so there is no up charge for 50 amp campers. This is a very clean park; however, the roads and some sites do get quite muddy if its rainy. There seems to be about 90% occupied with seasonal or annual campers. They are all well kept up sites. Not too many planned activities they just had one for the weekend. There are several self entertaining activities though such as the pool and I think they have mini-golf. The office closes quite early (about 5pm I believe) and if you arrive after that you have to raise someone from the front gate to let you in. The sign on the gate says to park in the parking lot for the night if you are a late arrival but I'm not sure if that is truly the case. There are limited pull thru sites. I would stay here again. Go visit the Rockford IL museum and take the tour of their old town. Check the internet to see if they have free Thursdays. - krisbw

We love staying at this campground. It is the only one in the area. We visit friends & relatives while here. It is convenient to a multitude of restaurants & shopping of all kinds. The sites are spacious, hook ups well situated, it is quiet & the people are friendly, & satellite signal & over the air antenna signal are easy to get. The drawbacks are there is no sewer hook up but there are two dump stations. There are no reservations & you can only stay two weeks. - Connie's Co-Owner

We made reservations the day before, the person sais they would leave a packet out since we would be arriving after 2 pm. When we arrived there was no packet but the gate was open to let school buses in, so we drove in. After we drove to the other end of the park we met a very nice man that said would help us. He called a woman and then led us to an Electric only site {we reserved a full hook up pull thru]. We told him we needed the full hook up site, another call to the woman and we received what we had reserved. The next morning when we were leaving at 10 am the gate was closed but were able to get out since it had a sensor. Stopped at office for receipt and office closed with no hours posted.
The park is mostly permanent and seasonal and seems to be well kept up. - 210george

We stayed here a couple of days while passing through the area. The sites are level and are well maintained. The utilities worked well and the Wi-Fi was fast most of the time. They don't have cable but we were able to pickup several over the air channels. The roads are not laid out well for big rigs but we didn't have any trouble getting in and out. Make sure you swing wide before getting to the gates. The GPS will get you close but you have to look for the campground's small sign. Follow the blue camping sign from the highway but turn left at the end of the road, our GPS turned us right so we had to make another approach. The host were not very friendly and just wanted to get us out of the office. We would probably stay here again if in the area. - dandg

We camped here over Memorial Day weekend. The office staff were friendly and smiling upon check-in. Our site was easy to back into and pretty level. However the sites were small and close to your neighbors. Our fire ring was 3 feet from the gravel road and parking area to the bathrooms. The fire pits were not dug out from the previous season and had weeds growing in them. The first night there was a thunderstorm, our power flickered on and off. The next morning some of the gravel roads were flooded and remained muddy the entire weekend. The bathrooms and showers were cleaned multiple times a day. With the contstant usage of the bathrooms, one out of the two toilets clogged, the management put an out of order sign on the stall door. The other ladies room on the far side of the swimming pond had 2 toilets, but no stalls or doors. Adults and children alike, would just roam through your site with no respect for your personal space. The beach and swimming pond were very small. With the temperature above 90 people were packed on that beach like sardines. Our children didn't mind, they still had fun at the beach. There are a few playgrounds, one is on the beach area. There was also multiple activities scheduled throughout the weekend for children and adults. - SkinnyMinny

There is a pool but they don't fill it. There is a playground but it's old and missing boards. There is a "kids barn" with activities which was a plus, but this is not a family friendly campground. The noise level is ridiculous & the seasonal campers are bad examples of how campers should behave. There are rules, but none seem to be enforced. There were many unleashed dogs, tons of people in the river when the rules state "no swimming in the river", there is a curfew for teenagers, but there were roving packs of them everywhere at all hours of the night, and there are quiet hours that everyone seems to ignore. We had to complain twice about the noise after quiet hours and to the owners credit, they did come out and take care of the loud people. The fact that anyone would loudly blast music at 1 AM and think that's OK, is ridiculous. This campground has a lot of potential, but you can tell that they just don't spend money on it. Everything needs remodeling and painting. The roads need paving and the bathrooms and showers need lots of work. Many of the toilets were clogged all weekend. The showers were old and we couldn't regulate the temp on any of them. It went from screaming hot to freezing cold within seconds. If you like to party and not be bothered with rules, then this is the place for you. If you want to camp with your family in a nice quiet campground, with nice facilities, then this is not the place for you. - MeMee4

Spotlessly clean spacious park with gravel sites and paved handicapped sites. Staff very friendly, firewood $5 for a nice bundle. All sites 50 amp with water, but no sewer hook-up. Two dump stations at exit. There is an equestrian area also. As it's a new park there are only small trees. We stayed for an Escapees event and others commented on it being a nice quiet park. We will return. - K&J

Clean open park, surrounded by farm land. Wooded area to the south. Nice flat gravel pads. No sewer at pad, dump station at exit. Bring an extension hose for your water. Sounds of trains passing occasionally. On a Wednesday the week before Labor Day weekend the park was deserted. WONDERFUL bike or walking path through fields and around a water filled quarry. I'd return if the park was not full. - RVStudent

This is a young park, meaning the trees are not big enough to give shade yet. You drive in and find a space you are comfortable with and the attendant will stop by later to collect the fee and pertinent information. It is a large, clean park with a comfortable amount of room between sites. All of the sites are 50 amp, so we used an adapter - and we lost power a couple of times with the AC going most of the time during the first heat wave of 2016. There are pull thru and back in sites on gravel with grass between each site. We stayed three nights, very quiet and comfortable. The park has water and electric only. Dump stations on-site. We would stay again. It's a long ride from I-80. We stayed in a 28' motor home with a tow. - Thirdtime

The bathrooms and grounds could have been better maintained, but we were there off season so that might explain it. We came in after dark and both of the campground hosts were out to dinner. We had a hard time finding our campsite and would have appreciated help. However, the park is so beautiful and peaceful that this more than made up for the poor maintenance. Our campsite was on the beautiful lake and the view was just wonderful. - FatSadieLou

Have been coming here for years when the kids were small, before full-timing. This park is a top camping draw for families from The City and fills almost every Summer weekend, during the week not even a tenth filled.
This park features a big fishing and paddle sports lake, no motors over 10hp. Buy a license! DNR Police are active here.
The day-use and camping sections are separate and distinct. There is a restaurant at the day-use side and a great camp store with fishing and camping supplies as well as food and ice cream treats on the camping side.
There are boat rentals at each location.
There are 150 camp sites, FCFS and ReserveAmerica. They are all back-in, electric only, level is debatable. The park works hard to keep the woods at bay and is constantly pushing it back, but the sites are still very woodsy, many are in twilight all day. The State Park has a booster club and many supporters. See this web site, not Illinois DNR, for lots of info about the lake and park, as well as pictures of the camping sites and lots of fish pics:
This is a camping park mostly tent camping, pop-ups, and travel trailers. Motorized RV are probably truck campers and small rv's. Check the photos in the above noted web site. Large Class A's and 5th wheels would have a chore getting in. There is a fire ring and picnic table at every site and there is plenty of grass around before giving way to the woods.
There are good hiking trails, including a formidable one around the lake.
Families and children play all day and never stop exploring the woods. This is not a quiet place...it is not supposed to be.
Besides the usual outhouses there is a single shower and bathroom building which, though cleaned daily, is severely taxed when the park is full. It is rather Spartan, at best.
Four host couples, scattered about the park keep things running smoothly without spoiling the fun. - Jack B
Jul 2015 - $15.00
Lived in the area before full-timing and know this park well. 150 sites: 60 FCFS, 90 Reserve America. It is a park all about a big lake for fishing, kayaks,canoes, and sail boards. No motors over 10hp. There is a day use area with cafe, boat rentals, and camp store. The camping area is separated from day use and also has a camp store and boat ramps. This is a park for tents, pop-ups, and small trailers. All sites are back-in, level is no way guaranteed. Many sites are very short, not designed for big Class A's or 5th wheels. The park is very heavily forested and camp sites cut into the woods. Camp sites are clear by constant use. Summer weekends are almost always full. Many miles of walking trails are mowed clear. Only one brick-and-mortar bathroom with two toilets and showers, the rest are all pit type outhouses. If possible, drive this park first and note the good sites. Because of its size there are five host couples on site and will help whenever they can. This park is basic but very nice. - Jack B

We have stayed here many times in 2004 and 2005. There are flush toilets at the Ranger Station. No reservations, but always a site except for holiday weekends. On holidays arrive early in week and get a great spot. Each spot has it's own water, elec, and fire ring. The wildlife in area is beautiful, crane, egrets, and several other fishing birds can be seen all day long. Additions of more tent sites expected soon. Residents of Kane County pay 10, others pay 15. - beckolette
