My bro said: A: ND, B: LSU, C: Wisconsin, F: UU (I've only been to LES & Vegas).
ND fans were nice. The stadium was 'meh'. LSU fans were pretty neutral. Wisconsin fans weren't mean, but were condescending (it was the game BYU lost) and he completely stopped rooting for uu after seeing how many (obviously not the majority) treated TCU fans (and specifically an elderly couple).
