The Mile O' Mud is a 7/8-mile oval track with a 1/8-mile diagonal lane slashed through the center. The racing lanes are approximately 60 feet wide. On average, the muddy water is four to six feet deep, with three strategically placed holes. The largest hole, located in front of the grandstand, is the treacherous “Sippy Hole”, named for the legendary driver “Mississippi” Milton Morris, Swamp Buggy King 1955, who repeatedly got stuck in it.
