I wouldn't of minded going - I've been every year except 2004, I just wasn't put up by the line up at first but it steadily got better and now I've no money left. Well, actually I've just not been bothered to do anything about it. Either way, Mastodon and Biffy Clyro...
Metallica in 04 was the only headliner that attracted my attention as I was a big 'Tallica fan then. All the others I've not really cared too much about. Tool and Metallica in '06 was nice but there was loads of bands during the weekend that had me hooked, they were just a nice bonus.
