Located in Long Pond, Pennsylvania, the Pocono Raceway--also known as the "Tricky Triangle" because of its unusual triangular or "roval" shape and severe turns--opened in 1971 as the Pocono International Raceway. The track has hosted NASCAR events such as the Purolator 500 and the NASCAR Xfinity Series as well as Indy Car races and ARCA Racing Series events. 2.5 miles in length, the track was designed by Indy 500 winner Roger Ward and has a distinctive design that features challenging turns modeled on turns at other prominent speedways such as the Indianapolis Motor Speedway and the Milwaukee Mile.
