I agree about Camden.
Years ago I was at a FR gathering there -— forgot what it was. My DH said to keep away from a certain main street while there. Well, when I left, I was looking for signs to the Garden State Parkway and realized I was on the forbidden street. This was when we still used maps. I didn’t dare stop to look at the map and FINALLY saw a GSP arrow. WHEW!
Camden was bad then and is worse now.
NJ has so many great places, yet dotted with terrible areas, but I guess that is true in any state.
