increasing the number of student seats available at LES and then letting UVU students use a UVU ID to get student season passes (at least for FB) to fill up the stadium with more crazed fans. I agree there are TONS of BYU fans at UVU that aren't BYU students because of grades, etc.
I don't have great ideas in terms of specifics, but in principle, I am a fan of the idea.
