Cardboard competition
U.S. Air Force Master Sgt. Steven McCabe, 317th Maintenance Squadron, cuts cardboard with a razor Sept. 4, 2012, during a build-a-boat competition at Dyess Air Force Base, Texas. Participants were given one hour to build their boats from cardboard and duct tape, and row from one end of a pool to the other without sinking. This year’s winner was the Dyess metal shop team.
