I think that is a great idea, giving discounted or free tailgating spots to greeks and or student groups like that on campus. Heck you could have a McVey Hall tailgating area, College of Business tailgating area, and have a competition between them for the best tailgate. Greeks wouldn't be a bad place to start as I think they would be the most likely to take that option up first and then once it got started it may spread to other groups on campus. Who knows if it would work, but I like the idea!
