July 4th brings a HUGE event back to Rocky Mountain Raceways as we present the 2015 Copper Cup Classic and the return of the Super Modifieds! For the first time since 2010, the Super Modifieds will do battle on the America First Credit Union Super Oval, turning laps in just 12 seconds! These hot rods are truly something to behold. Several other classes will be competing, including the Brandon Park Roofing Figure 8 trains! We conclude the night with a spectacular fireworks display! Gates open at 4pm, with heat races scheduled for 6:45 and main events to follow!
