Tom Corcoran, a freshman from Chicago studying physics, paddles aboard the “R.S.S. Raincheck” as he nears the finish of the 43rd Annual Great Cardboard Boat Regatta on Saturday at the Carbondale Reservoir at Evergreen Park. “We thought everything was going to go good and then the whole boat kind of collapsed and then we had to kind of just go with the flow,” Corcoran said. “Probably about halfway through the whole thing just caved in on itself and looked like it was near the end, but we kept on trucking and survived.” — April 30, 2016, Carbondale, Ill.
