I mentioned to Surly in the comments that I've no regrets for my career choice as a shop teacher but I do wish I could have worked with some of those master fabricators on the Champ cars. The drivers usually get the glory but it's the mechanics and the builders that make it all possible. Now the Indy/Champ dirt/sprint/midget all use carbon fiber or fiberglass for the body work. There's still plenty of work for a first class panel beater doing restoration or custom work but growing up in the 50's & 60's reading Rod & Custom, Hot Rod and all the rest, I was really impressed with the race cars and the true customs of the time. Forget the billet and the rat rods. Look at the work that was being turned out by the custom guys like Barris, Jefferies, Alexander, Roth, Starbird, Cushenberry, and all the rest. Those boys had it going on.
Life is just too short to be able to do everything you want to do, it seems. Of course sometimes talent is the limiting factor. That's why I was never a left-handed reliever but I'm hoping I've still got some time to learn a bit more metalworking, however.
