I was riding with a group on Memorial Day weekend in Madison, WI a few years ago. It was cold (~40F)and raining and about half the group turned back after about 10 miles. I continued on with four others and one of the guys proceeded to get 3 flats in the next 10 miles! I froze each time we stopped for him to fix it. Why couldn't he flat next to a gas station so at least I could get some hot coffee
