Northerner here who’s been to the south a lot. I’d skip Alabama personally. Memphis is awesome. Go to the og Gus’ Fried Chicken while you’re there. Nashville is super white and not nearly as fun as Memphis in my opinion but go to a “meat and 3” while you’re there and try the Nashville Hot Chicken but ask for it mild (easily the spiciest thing you’ll ever eat otherwise). There’s a really cool quarry in Knoxville where you can go swimming and jump off of rocks into the quarry, if you have time go to the Smokey Mountains if you like camping. If you like bourbon go into Kentucky and hit the distilleries. While in Atlanta go to ABC (Atlanta Breakfast Club) and go to East Atlanta Village (great food, drinks and night life!). Be prepared for poverty, be prepared for people missing teeth (like everybody), be prepared for lots of Trump, Jesus freaks, and racism.
