1. You're right, it's not as loud as everyone writes about. It is, however, 'West Coast Loud'. The people who write about Autzen have most likely never been to Death Valley, but it's probably as close to an SEC atmosphere that the PAC-10 has.
2. My favorite part of the pre-game atmosphere was the Pep Rally they hosted in what I guess was their indoor practice facility. It's a great idea, and basically took the place of tailgating for quite a large number of people. There were about a dozen or so in our group, but they welcomed us in, and we had a large time. Key point: they served alcohol, which made everyone quite happy. (Of course, this was all before the game and the post-game shouting matches and near-brawl.)

That's right -- the girls KEPT THEIR CLOTHES ON the whole time... They danced in bikinis. Needless to say, we bolted fairly soon after discovering this tidbit. Very strange.
