Pittsburgh is fantastic - I'm from the other side of PA, Bethlehem, north of Philly. Don't get me wrong, Philly's a great place too, but there's this gritty funky charm that appeals to me about P-Burgh.
People talk about the bars, the defunct steel mills, the cranky old people, but they're everywhere; but what about the cool jazz scene, both amateur and professional. I like the people there, my mom still has friends there, and I would live there if not for my premature arthritis which would be aggravated by the weather.
Pittsburgh is pretty cool - I would move there in a second if I could.
