Darryn Dushane, left, a substitute teacher at Lewiston High School, guides a group of students down the Androscoggin River between Lewiston and Auburn on Saturday. Eight students and three adults paddled two whitewater rafts seven miles downriver to Durham to explore the “greatest resource in Lewiston/Auburn.” “You get to see parts of Lewiston/Auburn that nobody ever gets to see,” when you’re on the river, said Dushane. Clockwise from left are: Dushane, Gray-New Gloucester High School freshman Tara Chase, Lewiston High School freshman Martin Ford, LHS freshman David Carvalho and LHS sophomore Paul Romanov. LHS Principal Gus LeBlanc made the trip on another raft.
