The tourist areas in the city of Baltimore are clustered around the Inner Harbor in a “Green Zone”. Canton and Fells Point to the east and Federal Hill just south of the harbor. What most out-of-towners fail to note is that these upscale yuppified neighborhoods are just 10-15 minutes’ walk of less by trot to the worst ghettos imaginable. The buildings in these slums are not bad, its the humanoids spawned there that are the problem with the yutes the worst of it. If you are visiting and maintain situational awareness and always have an exit in mind, you will probably be OK. I forget who said it but it is true that the one who keeps its head down gets eaten.
The only trouble I had was with some white yutes who were offended that the local chicks preferred sailors to them. Came close to blows but not quite when some adults happened along, called the kids "glue sniffing winos" and shooed them away. I don't recall seeing any blacks then other than some of my own shipmates.
