Just to Help out:
The NCAA rule is that no alcohol may be sold at a sporting event which is ON CAMPUS.
Hawai'i plays at Aloha Stadium, and thus serves beer. Same for Tulane, Miami, etc. Apparently Houston's stadium is technically "off campus" so they can get away with it. I don't know where I might find that specific rule, but that's my understanding.
I assume your stadium is on campus but I could be wrong.
