Another great concert was the Van's Warped Tour in 2000. This was when it was still a true punk show and hadn't sold out to the masses yet. I remember that concert vividly in Orlando at the fairgrounds. So many bands that I loved played that year:
Flogging Molly
Green Day
NOFX
Unwritten Law
Bosstones
Avail
CKY
Suicide Machines
The Dickies
MXPX
Save Ferris
LB Dub Allstars
Awesome time. Photo below of Suicide Machines on the second stage near the end of the concert at night.
Sorry for poor quality - disposable camera pics + zooming in on computer = shit.
