That must be why I just found it in the Oregonia mountainbiking route stash! Must have tucked it in there way back in September.

Yellow's got it right. The route snakes and snakes and snakes up to Whydaho. The third stop in Lewiston, Yewtah, is visited twice by the 100-milers. You ride a 20 mile loop into Whydaho between the two stops at it, so it is easy to reduce your ride to 80 -- certainly still a good ride.

I have several photocopies here. You want one? PM your snail mail address. I have a scanner at work and at home but neither is set up, so you'll have to wait for Mr. Postman (er, Postperson). The map describes all 3 routes and isn't easy to follow but you'll understand it with patience.
