Logan Heights/Shelltown. And what about LA: Watts, Compton, South Central.
This being said, I’ve driven (and walked) through South Bronx, Newark, and Spanish Harlem in the day. No real issues, probably would avoid hanging there at 3 am alone. I live about a mile from Spanish Harlem and had a good friend who lived on E 105th St whom I’d visit regularly. Used to live in West Philly, and took Baltimore Ave. out to the ‘burbs on a regular basis.
Camden is a whole ‘notha ball game, but it’s comparatively small.
