Although I've been living in Oklahoma for a long time, I was born and raised in West Baltimore. The city is NOTHING like it was in the 60's and 70's. Like you said, there's been a mass migration of folks southward into the Maryland and Northern Virginia 'burbs. Along with the exodus from D.C., the end product is that the political color of Northern Virginia has changed from red to purple to blue. From what I've heard, even the more southern areas like Manassas and Woodbridge are undergoing this demographic shift.
As someone said on a (local Baltimore) talk show today, just like locusts when Leftists/socialists ruin one place they move on to a nicer one.
In the ‘60s, I actually worked in the West Baltimore neighborhoods made famous on TV crime shows, and felt totally safe on any street there - (in the daytime), as a young blonde Public health nurse.
I cannot imagine going into those houses today to visit clients.
