Philadelphia makes me think of two things.
One is the Philly Sound, which I love. Gamble and Huff, all that stuff, brilliant, life-affirming music.
The other is that I spent 2 or 3 days there in the late 1980s. All i can remember is the Rocky steps (obvs), that LOVE sculpture thing, the area around the Greyhound station being particularly ropey even by the standards of Greyhound stations, and the Liberty Bell being massively underwhelming (see OT threads passim).
