The problem is that there's such a limited market for Rallycross in this area. There are a LOT of wannabe's, but very few actually show up to an event. And then half the ones who do show up are the wannabe's who just want to watch someone else do it.
Maybe some sort of an entry level "rallycross school" event would help? Might get some of the wannabe's who would do it but are afraid to embarrass themselves to come out and learn.
