The Rose Bowl is generally pathetic as well. BYU will never be Death Valley or the Big House or anything like that. Too many sober folks in the stands at LES.
Also, I've been to a packed baseball game at LSU against a Top 10 team, and even in close stretches or exciting parts there was nowhere near the noise you hear at a decent BYU game. That statement made you lose all credibility. I think you need to get out more, and you should pay attention to all the things that have already happened in the last 2 years to improve the LES game-day atmosphere. It's much better than it once was. BYU will always have a great, but not elite, game day atmosphere.
My football ranking of games I've been to:
1. Ohio State
2. Notre Dame
3. BYU 2009 vs. Utah
4. Utah 2010 vs. BYU (I figure those are good comparisons, although I will say "normal" non-rivalry games are slightly louder - not better - at Utah)
5. Utah State
6. Indiana
7. UNLV
