Seriously, I lived in NJ for four years and spent a lot of time in the city. Unfortunately, it was at sort of a low ebb period when crime was bad and everything was filthy (mid-late 70s).
Great Yankees team though - Nettles, Munson, Hunter, that gasbag Reggie . . . and the inimitable Martin.
The slums of that era are now $3 million condo lofts.
