We just returned from Edisto Island which is, hands down, my favorite vacation spot. There are no hotels on Edisto, no retail chains unless you count the Piggly Wiggly grocery and the gas station which has a Subway/TCBY. There's very little to do that costs money. The serpentarium, a few local restaurants, two book stores and about five or so gift shops dot the island, and none of them are on or facing the beach. Cellphones don't work well there.
We were blessed enough to stay in the campground at Edisto Beach State Park with my parents. Our campsite sat right next to the salt marsh, which holds a beauty all its own. Just across the street from us (and past a row of campsites) were the sand dunes and then the beach. Interestingly, the beach had just regone a massive restoration project that finished while we were there. This picture to the right is of the state park before. Now it's at least twice as wide!
Anyway, I did a lot of observing my children's joy and will post my thoughts when I get them together.
