I never heard of the Keystone area ever being called Potlicker. The now Carver area was called Potlicker.
Technically you are correct. The Potlicker area was not in old Keystone, but sorta between there and what is now Legion street toward Broadway. This was back in the very early '60's. Maybe there was more than one Potlicker? I guess which ever area you were in, it is a matter of what the neighbors called the other. I remember the Carver and East Fairview/ Millard street area being called something akin to N word town. Of course there was old Shacktown to the east of Highland, between the railroad bridges towards Maupin Row and Rich Acres. All that stuff was so long ago that it's hard to be 100% sure of my aged memories!
I did make a terrible mistake in my post to the OP, I had Mary Key street up in Keystone confused with Mary street, which is clear on the other side of town, my apologies! But back to Keystone..........I wasn't raised there, I was on the other side of Sell's Crossing, East Maple to be exact, but had many good friends from Keystone. It was actually one of those "other side of the tracks" things, physically, not economically or culturally! Heck, you could throw a rock between the two. My late wife was a good ol'e Keystone gal and the most wonderful person ever. Got any good Keystone stories? I'd love to hear them.
