This Sunday night, August 11th is the 20th annual Town and Country Fair Stadium Motocross in Washington, Missouri just west of St. Louis. This is an AMA sanctioned event with a $10,000 purse! The stadium style track is built by Chris Blakenship of Dirt Wurx -- who builds all of the Supercross tracks across the country. Nineteen classes are available to choose from so anybody can race in front of the massive crowd that this fair always gets.
