Oh, beautiful Pittsburgh, comedy mecca of the... well, nothing. But there's always a lot of comedy going on in town, and I know there are a few of us lurking around on AST. (Who haven't left for NYC yet.)
Just as an FYI, there's a site aggregating all (most?) of the comedy events in town: http://www.pghcomedy.com/.
I don't just mention it because they're featuring my blog on their front page, either. But WOW that helps. Big time.
