Colby Bettens, 14, of Concord, N.H., takes a turn towards the end of the Dirt Serpent trail on bikes he and his father rented for their first time riding at the Mount Sunapee Resort in Sunapee, N.H., on July 14, 2018. After taking a chairlift ride to the top, the mountain bike trails are all downhill — they opened at the resort seven years ago. (Valley News – Geoff Hansen) Copyright Valley News.
