The 30th Speedway Motors Heartland Nationals Presented By BASF is coming up in less than a month and will be hosted at the Iowa State Fairgrounds in Des Moines. If you’re looking to spend your July 4th weekend in the sun surrounded by hotrods, customs, classics, muscle cars and trucks, Heartland Nationals is the place to be. A highlight of the show will be the Goodguys CPP AutoCross Series. Spectators will have the opportunity to watch former IndyCar driver Robby Unser pilot a custom 1970 Chevrolet Camaro Z/28 built by Speedway Motors.
