When he was a senior in college, Edwin Collins decided he wanted to take a solo bicycle trip across the United States. He prepared by taking training rides on the East End that started and ended at his parents’ house in Montauk, and he often rode home after midnight, after his dishwashing shift at Gosman’s Dock restaurant. The journey ultimately took him from Portland, Ore., to Beacon Hill in Boston, where he pedaled up to his sister’s apartment and was greeted by cheers from his family.
