I thought the OU atmosphere was pretty boring for such a big time program.To me there is a big difference between hate on the court/field and animosity between the fan bases. We all despised the flag game with KSU,and disliked Huggyball and Holgerson and the dude who bumped Wally in FB. Doesn't mean their fan bases are bad especially if you ignore the internet trolls. I've been to all but Austin and Lubbock and the only fans I've never really liked were OU they were just snobby and not very friendly, not personally mean.
I thought the UT fans were pretty fun after a game in Austin. The town itself is pretty awesome though. Think if Madison WI was a warm weather town.
