I visited that area during the summer a lot when I was in high school. Beaufort has a covered skate park, it might have lights by now as well. I don't remember it too well but think it was kind of shitty. Hilton Head isn't far from there and has a park. Also in Hilton Head there is a post office that had some good stuff to skate, don't remember which side of the island it was on though, and one of the schools on the island had a decent gap. That area is pretty close to Savannah though and that was always a fun town to skate, lots of parking garages to skate and some had ledges or banks inside them. It's been at least 6 years since I've visited that area though so things could have gotten better with skate parks or they could have closed some of them down by now.
