This 3/8 mile clay oval track is one of the oldest in the nation. A 1/2 mile horse racing track was created here, along with the Mercer County Fairgrounds, in 1873. Motorcycles took to the track in the late 1940's, and the first auto racing event occurred in 1951 on a reshaped 3/8 mile oval. Sprint cars, modifieds, and stock cars race here on Saturday nights.
