This tight high-banked 1/3-mile bullring presents NASCAR-sanctioned 358 dirt modifieds and late models every Saturday night. Over 50 modifieds typically attempt to qualify at Grandview every Saturday, making it one of the largest field of weekly competitors in a single division in the nation. Highlighting Grandview's annual calendar is the big $20,000 to win Freedom 76 for the modifieds each September. Throughout the year special events take place for sprint cars, modifieds, and more in Bob Miller's Thunder on the Hill Racing Series.
