As someone who's originally from Bucks Co I agree with Philly being annexed to NJ. Just call it the Greater Camden Region.
I worked (just outta high school) at the oldest gas station in the US. It's still open...and it's still full serve.
My Daughter went to Rutgers in Camden, and when I went to go visit her, "I" was packing "Peanuts" for the local natives, and still felt uncomfortable there.
