I've been to 8 Indy 500's, AWESOME, especially when viewed from the Snake Pit, LOL!
I used to go to Louden NH every year before IRL.
Some year I'll get it together enough to drive up to Montreal for the F-1 GT.
The midwest has its own fender-free format....USAC et al.
I also would like to go to the 24 Hours at Daytona (even if they do have fenders)
