Lifelong PA resident here, still live less than two hours from several sprint car tracks. I have seen a lot of winged racing and still do. I have seen so much winged racing I kind of get sick of it. I started following non wing racing in '84 and its my favorite and have waited a long time to see it here.
Back to our winged stuff, I think the car counts are decent here but some teams are running out of parts. I don't believe sprint car racing in PA is suffering too much, not really seeing over saturation. Plenty of 305's, plenty of 358's, enough 410's to go around. I've been to 14 races and I think they all have paid a minimum of 5 thousand to win. I have to scratch my head when I see some Indiana tracks only paying 1,500-2,000 to win with basically is the same general admission price as here in PA.
