We camped out in Idaho's Silver Valley, and nearly froze overnight. The temp was in the mid 30's. Next morning we rode to the top of Lookout Pass on the Idaho Montana border. Froze again at the top of the pass and on the way back down. Clouds moved in and there was talk of snow flurries! We didn't see any, but it was certainly cold enough. It was a very pretty ride through cedar forests, with lots of little creeks flowing over moss covered rocks and logs. Next time we'll dress a bit warmer. bikerHen
