I was born in Atlantic City. I lived in Ventnor, the next town down, till I was 15. From then on, I lived mostly in Atlantic City until about 1990 till I moved down here to Florida. Atlantic City is dangerous! From Albany ave down to Jackson Ave, which is the border to Ventnor, it's not quite as bad and is mostly residential. It's called lower Chelsea.
There's not a way in the world that I would sleep in my van in the rest of Atlantic City without a loaded pistol under my pillow. Even then I'd sleep with one eye open. I'm not a drama queen. I'm 5'11" 210lbs and can take care of myself. I'm telling you this out of experience and some really bad experience at that, not second hand knowledge.
Some areas in the city look pretty nice now. They're NOT.
The only bonus is that the police have real crime to deal with and they don't sweat the little sh**
