Watkins Glen Indy Car Race Question?

I wrote a book about American Open Wheel Racing and I'm going to sell it via internet. I'd like to drive some traffic to the book site by ping out fliers at the Watkins Glen IRL race in July. If I put my fliers on cars in the parking lot, will I get kicked out? I'm bringing family and friends so I definitely don't want to cause trouble but I'd like to get the word out there about my book. What do you think?
