I had the same kind of question... I do know that Powri has thrived by running smaller tracks.

Would have like to have heard more about the Silver Crown division. One of the things that has stuck with me since the Davey Hamilton departure was in Hamilton's exit interview he talked about how he had wanted to turn the Silver Crown races into more of an "event." Again, don't know exactly what he meant by that... but with sponsorship, money, prestige etc... those races at the fairgrounds should be a big deal.
