Aeroblue,
OK, we've been to Ubly, but not with the really fast cars. We took the daughter there with her street Grand Prix a few years ago to let her get the hang of staging. We were there in the Mid '70's too with a '69 GTO (guess that's telling our age). I remember we borrowed some slicks from someone at the track and ended up driving home to Royal Oak at the time with them on, and it rained!! Man was THAT fun!
