It would be more but either my friends flake on me, or we get there late. I've missed the Vandals, CroMags, MDC, and Siouxsie because of this. :(
Greatest punk show? It's a tough call between:
--this one show with two stages: right side stage had bunch of bands like The Offspring, the Vandals, NOFX, and Rancid-- other stage sucked.
--Original Misfits tour with AFI
--No Values (TSOL, The Addicts, Original Misfits, etc.)
--Halloween Punk Rock covers show with local bands doing amazing covers and impersonations in a small Halloween club setting (Misfits, At the Gates, Bad Religion, etc.)
