ICE. I was a dedicated commuter and rode as much as I possibly could. One of the first few years I rode on my way to work (dark) I came upon a place on the MUP a waterline had broken and poured across the trail. I did not get hurt but I certainly had no control. I quit riding below freezing after that. I am in Indianapolis and, as the snow is melting I was just thinking about gettin my Surly ready to ride. Soon.
