INDIANAPOLIS, IN:  O'Reilly Raceway Park at Indianapolis, known as Indianapolis Raceway Park until the 2006 purchase of naming rights by O'Reilly Auto Parts, is a multipurpose racing facility located in Clermont, Indiana. It is not to be confused with Indianapolis Motor Speedway (IMS), which is often referred to as a superspeedway, although its construction vastly predates the use of that term. Surprisingly to some, the vast majority of motorsports events held in Indianapolis are held at Raceway Park, including a NASCAR Camping World Truck Series race, a NASCAR Nationwide Series event, a midget car racing event, drag racing and road racing.
