Re: NC SC beach camping...
I would add the SC State Parks to that as well. We've only stayed @ Myrtle Beach State Park, but I have heard/read good things about most of them, and they're priced well for a budget.
As for NC beaches, I'd like to hear others thoughts as well. We love the OBX but haven't "camped" there yet. I would give strong consideration to Camp Hatteras though...
