Islip Speedway was a .2-mile (320-meter) oval race track in Islip, New York which was open from 1947 until 1984. It is the smallest track ever to host NASCAR's Grand National Series (now the Sprint Cup Series), from 1964 to 1971. The first demolition derby took place at Islip Speedway in 1958. The idea was patented by Larry Mendelson, who worked at Islip Speedway.
