I'd love to hear the rationale behind "South" vs. "Good Part of the South".
I'm in GA now, originally from FLA, so I'm good on both counts.
I am assuming he means Miami and Atlanta.
The South's geography is a neat little paradox. If you go on a roadtrip from any Southern State to any other one, no matter which direction, every time you leave one state it's "I'm so glad to be out of Alabama... oh, crap, I'm in Mississippi". Every state is better and more delightful and worse and more terrible than its neighbor, so the grass really is greener on the other side as long as you never actually reach the other side. Ironically, I've always said this effect ends in North Carolina - once you're there, anything there or up the coast is always an improvement over South Cackalacky.
As a long-time Floridian, it's also its own little paradox: the further south you go in Florida, the further into the North you are. I'm up in Northeast Florida, but the panhandle and north Florida are essentially South Georgia or East Alabama. Gainesville's an exception, of course, but by the time you're down to the I-4 corridor, you're in a more northern area, and then Miami is essentially what would happen if Havana and Boston had a bastard lovechild that couldn't be bothered to go see the Dolphins/Canes/Marlins/etc. unless Tim Tebow is there.
The important thing to keep in mind, though, is the sage counsel of a very intoxicated fellow from South Carolina we ran into after the Florida-Georgia game in the mid to late 90s. It's really hard to dispute the tragic beauty of the sentence: "I'm from South Carolina, and you're not, so you suck and I don't."
