My state was neutral during the Civil War, but my hometown was split in half. The North side was for slavery & the South side was against. The stores on Main have doors on both sides, so they could get business from both. :)
From the same time period, I believe it's still illegal for African Americans to be out after dark. (obviously it isn't enforced anymore).
It's also "Black Squirrel City" (there are also some interesting black/brown combos running around).
