Ok... Since I'm the guy who works directly for Tim Dibble and Hartford Speedway and formerly Thunderbird Raceway, I can safely say that Dibble has absolutely NOTHING to do with Thunderbird Raceway in Muskegon, MI. Any rumors on that are completely false.

The current owners of Thunderbird LIVE in Hartford, MI, but have no affiliation with Tim Dibble or Hartford Speedway.

Someone could buy T-Bird on the cheap.... (I talk with the owners every day).

As for Hartford & USAC... the problem with Michigan is that hardly anyone even knows what USAC is let alone a Silver Crown car.. (sadly).
