While my thesis has always been that punk and baseball share a symbiotic, harmonious relationship, there have been glaring instances where that simply isn't the case. The most obvious and largest example of this occurred in late August 2006 in Pittsburgh's, then newly opened, PNC Park. Punk cover super band Me First and the Gimme Gimmes were booed of the damn stage (on a side note, it's fun finding Punknews articles with no cited sources). If you know about anything about this band, then you know this did not faze them in the least and they were laid back enough to laugh the situation off. Here is the only footage of the show that I could find on the webs. If you have or can find better footage (preferably with more drunken heckling), let me know and I'll post it.
