If we can get the crowds up we can sell booth space to businesses as well. For example I work for University of Phoenix. University of Phoenix would love to come set up a booth at the race track and possibly pay maybe a hundred bucks for the ability to do so.
What I mean is once the crowds get large enough, we can invite vendors to come out and set up booths to push products or services for a fee. I don't know how this will affect rider sponsorship or anything.
