Jersey City is even worse. Trash are everywhere on the street. Black people are wondering on the street with a bottle of bear.
LA downtown is no much better.
New Orleans has so many homeless people tenting under highway.
Chicago Chinatown and nearby area is the place no one want to go again.
Seattle is so pretty but has so many homeless people. I encountered at least 20 daytime nearby major streets.
The city I like is DC. Houston and Miami are OK.
Of course, one can always find good part of any city, which is quite, less traffic, no people wondering on the street.
