I went last year (for free!) and it was awesome...and I can walk to Seattle Center from my apartment. I even had the "bonus" of the sweet, sweet sounds of the Wu-Tang clan blaring into my apartment window at 11 PM at night.
i kinda stay away from that place because it's just so echoy. my roomate saw bob dylan there and said if you get up front-center it actually sounds good... but you probably have to work for that. and hold your pee for a long long time.
so i think the prices went up as of today! darn... i guess the lesson should be to NOT wait until the very last minute to get your tix! wouldn't want to miss out on this insane event. on a level of its own, it's going to be like nothing else... AHH! :]
