Kev, I agree, I just don't see the groundswell of interest in road racing. Is there a place for it? Certainly. Is it good? Absolutely. Is it financially feasible, for a racer, no for the reasons you mentioned, and even from a promotor standpoint because it would take a lot of land and development to build anything decent.
I also agree that there are tons of cars showing up at T&T's and "street night" at the local track. I know they do here. One could think drag racing is "dying" by watching the ESPN coverage (nonexistent); the empty seats and the big sponsors leaving.
But, what a lot folks don't seem to realize is that Pro drag racing does not necessarily indicate the sport's health. I really think outside of the NHRA Pro show, the sport is alive and well. Pittsburgh had over 400 cars in the pits the other night...there were over 60 dragsters alone.
