In the late 1980’s, a few college friends in Buffalo, New York created a game called 'Trash Can Frisbee'. Players toss a disc toward garbage cans where a partner slaps it in for points. The sport was mostly played in backyards around Buffalo for years. Now, it’s known as KanJam and played at tailgates and parties all over the country. But, as Daniel Robison reports, the sport owes its success to gym class.
