I'm interested. I went to it last year, and it was incredible. Got to meet a lot of the race crews, drivers, etc, there was lots of good music, activities, food, etc. There was also an awesome car corral for car clubs last year - after the saturday races, the owners of those cars got to take a lap around the course! I didn't fork out the money to do that, but it was an incredible time.
Actually, I had more fun at the Baltimore Grand Prix than I did at the Indy 500 this year....there was just a lot more of a variety of racing and things to do.
