Hey Alf,
That looks like my old
EggCamper and Bill's
Casita in the background of the second photo. Do you remember playing Hand & Foot with us?
I like Myrtle Beach SP. It has a wonderful beach. It can be a bit noisy though when the Air National Guard is practicing "touch and goes" at the nearby airport. Huntington Beach SP, about 15 miles south of Myrtle is also very nice, but can be difficult to get in.
James Island, near Charleston, SC, is a county park, very nice. Oops, Norm, I see you've mentioned that one while I was editing.
Skidaway Island State Park near Savannah is nice. They have septic at many of the sites and Georgia grants senior discounts to out of staters.
