Watkins Glen International (nicknamed 'The Glen') is an auto race track located near Watkins Glen, New York, at the southern tip of Seneca Lake. The facility is owned by International Speedway Corporation. It was long known around the world as the home of the United States Grand Prix, which it hosted for 20 consecutive years (-), but it has been home to road racing of nearly every class for over 50 years, including Formula One, the World Sportscar Championship, Can-Am, NASCAR Sprint Cup Series, and the IndyCar Series. The circuit has also been the site of two concerts: the 1973 Summer Jam, attended by 600,000 fans, and Phish's Super Ball IX in 2011. The Watkins Glen International race course has undergone several changes over the years, with five general layouts widely recognized over its history. Currently two distinct layouts - The 'Boot' layout (long course) and the '1971 Six Hours' layout (short course) are utilized.
