Tim, that's some great information!
Exacly what I'm looking to hear, and you can't get too much info on the risky side of the discussion.
I somewhat get the cost of racing, in the 90's I road raced a Ducati, not the big dollar liquid cooled stuff, the cheap(

) air-cooled 2v Super Sport. I did all the fabrication and maintenance on my own and had a great builder/tuner build the engine, and also worked with a great local suspension guy.
My wife (girlfriend at the time) helped me on rece weekends, and maried me anyway
So yeah, it's not going to be cheap, but I'm looking for a way to go racing because I miss it a bunch

Bikes are great but the ground seems to get harder and harder as I get older.
That and the car world in general is also very family friendly. part of the appeal of the vintage world is that they limit high-tech stuff and your ride can't get out-dated
Not looking to win a championship of any kinid, already did that and have a great, and tiny, trophy to show for it
Just looking to burn some tires and have fun.
Jeff, great links! That shelby stuff is great, I was at the Shelby place in Vegas a few months back
