Help Identify North Woods "6 Speed" Tandem?
For what it's worth I picked up a NORTHWOODS SAFARI on Craigslist about 2 months ago. Mine is also a 3x6. It has a sticker from "Scotts Cyclery"  of Willimantic,Conn.  The sticker is not the typical square type that is on the seattube. This one runs along both seat stays.  A clue that it may have been a low end bike is that it says "quality bicycle" on the headtube badge and was made in Indonesia. I would do a little preemptive maintenance. Most lowend bikes I have worked on seem to have little if any grease in the bottom bracket, headset or wheel bearings. Just use it and enjoy it.
