In defense of Philly(if not lazy online list writers), Philly is the biggest city in the state so its understandable people default there. PA is one of the most regionalized states in the country so we can keep all the cultural little nooks and crannies to ourselves. One thing I sorely missed when I lived out of state, PA has a lot of great regional culture(I didn't even know how much food I grew up with was specific to South Central PA until I left).
