We were just talking about that here not two days ago. This is SO frigging silly. We'd be there, for two weeks (Nat'l, big $$ race, Div7 Race), if it weren't for this silly "one class dropped" thing.
I understand it at tracks with limited space, but holy cow, if there is ONE track in the country that could take on all comers, it's Vegas. Virtually unlimited parking space, no curfew, good weather. It makes no sense.
And NHRA is giving up a lot of dough. I'd bet you'd fill a 170 car SC field (with the races the next week), that's something like $40,000 in entry fees.
