I do think the Outlaws are better than ever right now. Saw my first Outlaw race in 1978. It was run without wings. Even with a horrible format that always starts the fast guys upfront, their features are usually good, but they have to get in lapped traffic. That is where the wing guys really shine. The All Stars are stronger than have been since Guy Webb nearly destroyed them. Beyond that I don't see any real growth in wings. Part of that is it's so divided between 410, 360, and 305.
I feel non wing is in a growth spurt in PA. Between Kutztown and the USAC east coast sprints, there is a pipeline to develop new talent. Enjoy what you want, but the winners in both are the only ones really making money
