As for courses that have regrettably closed, I'll put in a word about Winyah Bay in Georgetown. It was owned by International Paper but my family were members there back in the 1960s. It was an excellent beach-style course with only nine holes, but it had two distinct sets of tees that made every hole play differently the second time around. Later, they added nine more holes to make it a par-70 18-hole course and it was nice and it was fun - and pretty. Several years back, it sadly closed to become a housing development which has barely managed to launch.
