Any last minute advice for an Indy 500 rookie? I have my tickets for Sunday. What should I do for parking? What does everyone think about Carb Day, Is it worth going? How about the parade?

I am already planning on going to the three USAC shows the days before the race. Any thing else that I should plan on doing? I heard that some of the race shops in the area will have open houses. Is there a schedule for that.

Thanks
Jon
