First off, Bob, welcome to ORR.net. Jump right in and join the fray.
Santee Lakes Campground looks nice, even though I usually prefer state parks. As we would be staying for about a week, though, having a sewer connection as an option might be nice. Do you recall what the rates were?
That looks like a spot with plenty of amenities. And it's not too far from Congaree NF.
Thanks for the heads up.
