I have never ridden in the mountains of Colorado at any time in my life, but I do know about the sudden change of climate. I was stationed in Cheyenne, WO back in 65 and 66. Went to a downtown movie on a July evening with a short sleeve shirt on and came out of the theater to freezing temperature and a hail storm. Next morning there was snow on the ground. I took photos and sent them home to my parents because nobody would believe me if I told them it snowed in July.
