Other than Hardeeville, Sun City, Bluffton areas, your next option is Ridgeland at exit 21. They have nice areas as well as bad, just like everywhere else. 35 mins to Sav. by 95/321.
If you notice the extra swamp land everywhere between Hardeeville and Ridgeland, its owned by one family since before the civil war. Called Okatee Hunt club, its something like 60,000 acres, all for their hunting pleasure. Infact, its mostly big hunt "Plantations" with another, Turkey Hill at 30,000 acres, that make up most of Jasper county. Pulp pine tree farms make up the rest.
The further away from the coast the cheaper it gets $20,000 acre by I95, $5000 around 321ish. Food sucks, unless you like McDonalds/ Burger King. No bars, 2 food stores that I swear are where the bad/ old dated meat is sent. Schools and Industry not the best. Gas is always $.20 more at the gas stations.
But good people and a great place to live if you don't have to worry about that other s--t.
