So to use your logic, on only having to pay once. It would make sense that the promoter would only have to pay once. After all, it is only one driver.

When I was in Texas, it was common to have drivers in mulitple classes, and the driver had to pay a pit pass per car that he entered. It was known and accepted.

I think that this horse is pretty dead. BTW How many promoters leave the sport after three years. I think I read that it was over 50%. I guess that they were making too much money to continue.
