I remember this "series". The problem was that, while it seems like a great idea, it was not successful the last time it was tried. Only two guys made the 4 events. Dave Hauck won the series but he never got his trophy or any other recognition for his win. It was like it never happened.
It seems that the logistics are even tougher than before with the loss of PIR. Now, other than Chuckwalla, which has no place to stay anywhere close, the only Az options are Firebird (the tracks are not very fun) or Inde (which will take forever to get to, perhaps 8 to 10 hours).
For So Cal, other than Auto Club, the other tracks are a much longer tow for
Az guys and, with the economic situation right now, most guys are having to be selective about which events they spend their money on, which makes a long tow to an out of region event expensive and even harder to justify.
If you want to get this going, you might think about getting Dave his trophy, for the last one, before you start another one.
However, good luck with it.
