Awesome reviews everyone. Heres my ratings for all the bands I saw, since the review is late and the other reviews are pretty much exactly what I would say about this years fest.
Bands I saw:
Whitechapel (watched the show while in line to meet Anthrax): 8/10
As I Lay Dying: 8.5/10
Slipknot: 9/10 (would probably have been a 10, but by the point I was pretty beat, I put everything I had left in the tank into going ape shit during slayer's set).
