I was born in Camden sixty-nine years ago. From that day on, I never saw a reason to go back.
I don’t blame you; without family and decent work nearby, I wouldn’t be living here in NJ. A huge problem for the whole state is the loss of its younger taxpayers (who follow the companies that are leaving). It is a small enough state that you can live in PA (even keeping a NJ job if you have one). A friend works in NYC with a couple of people who commute from PA.
The battleship New Jersey is there, as a museum. So one reason to visit.
Thankfully you can get to her via water taxi from the Philly waterfront.
