I don't have any family in that area ... but I did have a cousin that did 2 years of college down there.
Yes it is right on top of Florida. The area is as flat as Florida and is one of the hottest parts of the state. Its half redneck, half college party town. They worship football and are considered to be one of the perennial contenders for a national high school football title. Its ~40,000 in population and the closest real city would probably be Jacksonville, FL. The population is dead split in half between white/black. Theres more women than men. The area has an aura of being a bit below the wage average. Theres no decent entertainment outside of fighting, drinking, and fornicating. I can't recall any lakes nearby ... but there is the Okefenoke swamp. It covers an area of about 30x30 miles. Theres an AirForce base to the NE outside of town ... so you get a bit of military leave traffic. It had the semi-air of a bohemian villa with all of the students. Lots of music and dope. There did seem to be a lot of theft... so locking your doors and cars is a must.
I couldn't live there simply because the place spends 3 months in the mid 90s @ 80+% humidity over the summer.
