I actually read an article from the MSN homepage about a lesser fortunate community in the panhandle where people couldn't simply just get up and leave. The case it focused on was an older man that had his driver's license expire when he went down to Florida and had trouble renewing, so he just didn't drive, when he gave his explanation, the police gave an authorization that allowed him to drive, and because he simply didn't have anywhere to go, he went from said community to Medart, FL, and hunkered down there for the storm, then drove back after it was over.
Searching this, there's more than one case of this down there. Trailer parks with residents that couldn't leave. It's a shame. A lot of the panhandle of FL outside of the three major cities (Pensacola, Panama City, and Tallahassee) seemed pretty rural when I was down there in the past. Southwest Georgia probably has more of the same as well and with there, there's the crops as well.
