Hilton Head native here, I don't think the HHI history is quite the same. Prior to Fraser kicking off the island as we know it in the '50s, it was basically just a handful of Freedmen farmers, Gullah natives and a rather large hunting reserve for the rich. Also, while some of the gated communities don't allow the riff-raff in, unless you decide to bike or make a restaurant reservation, some still do, most notably Sea Pines.
Also, the Town of is rather cognizant of their place as a very natural, family-friendly island and goes to great pains to preserve land[0] and limit what and how folks build[1][2] to preserve the nature of the island.
I think Kiawah or Seabrook up the coast make for a more apt comparison.
> Hunting Island, SC as well - Fripp Island is a gated community.
Wait, Hunting Island and Fripp Island are discrete, separate islands with Hunting Island being a State Park. What's the problem with Hunting Island?
