The Erie Canal Soda Pop Festival also known colloquially as the Bull Island Rock Festival, was a rock festival held on the Labor Day weekend of 1972 near Griffin, Indiana on Bull Island, a strip of land in Illinois but on the Indiana side of the Wabash River. A crowd estimated at 200,000 to 300,000 attended the concert, four times what the promoters estimated. Food and water were in short supply, and the gathering descended into relative chaos. After the show was finished, remnants of the crowd burned the main stage.
