In the 1970s, Indy car racer Wally Dallenbach took his winnings from the California 500 and bought a ranch near the Fryingpan River in Colorado. In 1975 he explored the mountains and mining ghost towns around his ranch on his motorcycle with his son Wally Jr. and friend Sherm Cooper. They loved the trails so much that the next year they invited friends Dick Singer, Art Lamey, Lon Bromley, Del Garnder, Ed Kretz, Al Unser and Bobby Unser. That first ride in 1976 needed a name and being Indy 500 veterans, the group named it the Colorado 500.
