Voltage and Current relationship in generation
As Brian says in comments, it's a matter of convention.

In network analysis, it's a common convention that the current associated with a device (generator or load in this case) has a positive sign when it flows in to the device. This appears to be the convention your text is using. 

Notice that this convention means that when a device is providing power to the circuit (like a voltage source or generator does), it will have a negative current. This seems anti-intuitive, but it's just a consequence of choosing a common sign convention for device currents regardless of whether they are sources or loads.

And, as Brian says, if current is flowing into the load, it is necessarily flowing out of the generator. So with the network theory convention, the signs of the two currents must be opposite, which is the same as a 180 degree phase change.


  i bet if i was a few hundered yards up the road at the first load point and i was able to look at the wave forms on an oscilloscope the Voltage and Current would be in phase again.


Because you would be measuring the current in the direction away from the generator and towards the load. If you turned your current probe around and measured the current going towards the generator, it would be 180 degrees different. 

In your original measurement, when you measured at the generator, you had the current probe/sensor pointed toward the generator; when you measured at the load, you had the probe/sensor pointed toward the load. So you got results that differed by 180 degrees.
