Philadelphia - Gotten to know you

Though we're in the midst of moving 3,000 miles away I still feel like Philly is a natural place for us in many ways. East Coast, mid-sized, music and activism in abundance, we have good friends there, affordable housing. I don't even know what it is about Philly that appeals to me so much because there are certainly other cities with the above credentials. Perhaps that it's a scaled back version of a large city like NYC but not Boston - a city I never see myself living in. It's somewhat large, somewhat cosmopolitan...but not overwhelming. This is quite possibly academic because a move back east is at least 5 years away I think.
