This is the last weekend that the Salute to Champion Jeff Gordon exhibit will be available for viewing at the National Sprint Car Hall of Fame and Museum. The exhibit features six different Gordon cars, including the famous rainbow-colored DuPont stock car in which Gordon won the first ever Brickyard 400. Also included in the display is a sprint car Gordon ran at Knoxville Raceway. Director Bob Baker says that the exhibit has drawn a lot of traffic to the museum, and they’ve sold hundreds of memorabilia items involving Jeff Gordon because of it.
