Bonnaroo was my first 3.0 show and I was extremely excited, especially after seeing The Beastie Boys (was that MCA's last show?) and David Byrne (somehow I called the "Air" encore. Byrne fans don't get as excited about stuff like that as Phish fans do)
about ten minutes into the DWD jam, I remember feeling that they had reached the doorway marked "best Down With Disease ever", looked at it for about 15 seconds, and then moved on without opening it.
I also remember the morning after that set, I was awoken by the main stage PA playing a loop of Trey's isolated vocals from the post-chorus of the Wolfman's, and it was awful.
