Never blame Bob or USAC for track prep, there is nothing that can be done to these surfaces as they are used year round by the horsemen, and there is now way around the fact that racing is a guest in someone elses backyard (on the miles). Worked with Bob for years and he has done everything he can. Given perfect conditions you might get a cushion at DuQoin but thats it. Stop and think about all the hot as hell day shows they have run, and there was never a dust problem on the miles! That did not happen by accident!
