This 6-minute video provides a sampling of the vintage trucks that attended the American Truck Historical Society's national convention and truck show May 24-28 in Des Moines, Iowa. The streets and parking lots of the Iowa State Fairgrounds were filled with rows of antique and classic trucks, and the 1,180 trucks at the event set a Guinness World Book Record.
