Mike Winck is an assistant U.S. Attorney in Knoxville, TN. He bicycles to and from his Federal government office every day. This winter, he had an apellate court argument in Cincinatti, so he rode his bike three days to make the court date. A business trip last spring to Columbia, SC took him six days by bike, round-trip. "I do it for my mental attitude and because I feel we drive too much in this country," Winck said.
