I think gulf side of Florida would be good. You can arm youself, you wouldn’t freeze if it happened during winter and you can heat up canned goods on the grill if the power goes out. Where I am you have to cross a bridge to get here. I’m sure they would be guarded in the event of civil unrest. At least that’s why I just retired here.
The big problem with FL is that in the event of nuclear war the state is full of high value targets. That said, the prevailing winds would blow any fallout from west to east and extreme SW Fl might be a good place to live out the apocalypse.
