New Orleans

"Being a post apocalyptic town's gonna be cool. Other towns'll be scared of us."

Ah, the Big Easy, famous for Mardi Gras, voodoo, and jazz music, despite not inventing any of these. Also hurricanes. The French have an embassy there. If you want to sound like a local, make sure you pronounce it with two syllables, something like "n'aw-lins".

Note: Tourists think they're hot shit when they attempt that last bit. To not come off as a douchebag, just go with "New-OH'rlins". Once you've lived here a couple years, your speech will naturally slur it down to "N'awlins," but don't force it.
