Named after Interstate 270, a highway that forms a 55 mile loop around the city of Columbus, Ohio, a 270 Power Hour consists of a group of friends driving around the entire interstate and taking a shot of alcohol each time an exit is passed. Be careful, there's 28 exits. Drive at 55 mph to achieve victory in exactly one hour.
