The costs of running pavement, first of all, tires in particular. You heat cycle a pavement tire and it will never be competitive again, so you're down two sets a night minimum. Most teams that do run pavement also test. More tires, more money. So eliminate testing you'll say. It's such a different animal from a car stand point and a driving standpoint, If you're just starting to run pavement you'll never be competitive against the pavement specialists who've done it for years without testing. Times have change, most of today's dirt silver crown cars are just longer dirt sprint cars with big tanks. Wouldn't even be feasible to run them on pavement, and perhaps not even safe. It's a catch 22. Between the death of all other pavement there's no opportunities for laps and with the expense and for the same reasons it's why the other series have died. Fan counts at these races aren't what they are on dirt, but nobody is going to watch 13 cars in which maybe 5 are competitive. And not very many people are going to go through the time and expenses to run 10-20.
