A favorite trout stream, has winding long road to it. More than once I and many others have run up on a bicycle club perhaps, but certainly a lot of bikes that hog the road refusing to get over into pullouts an let traffic pass. i think there have been a few accidents. Nothing like being trapped behind a flock of bikes, at 15 mph or whatever for many miles, with just enough blind curves you don't dare pass.
When we did get a chance to pass some of the Riders displayed their IQ for us, and some tried to crowd into the other lane to get you to back off and stay behind them.
