Why are people talking about Philly like it's a cesspool of humanity? It's one of the biggest cities in the country with loads of history, culture, etc. and just about as far from Vegas as DC is already. All the talk of him not wanting to play there is a lot more than "I think the city is dirty" or whatever (i.e., has more to do with, I think, him not wanting to be boo'ed forever - I doubt he ever envisioned himself playing there).
I'm sure his wife would be fine with it especially if they get over 300 million dollars to find their suburban oasis. The difference between the rich suburbs in the top cities is negligible.
