I've never been to Colorado, so I can't comment specifically. But around here, the cycling groups are very careful to ride in small, single file groups so as not to antagonize motorists. We want to be safe and welcomed. I just wonder if their are large groups of cyclists in Colorado who actually do block the roads. Anyone?
Yes, I was in Aspen one summer and large groups of cyclists blocked a twisting winding road. It was obviously an elite group training, and I tried to see if there was anyone famous, but they would not get single file or two by two. I had mixed feelings about it at the time.
