We have reservations at Ace Basin Campground in Sheldon SC.  They have been difficult to communicate with all along but campgrounds are hard to come by in this area so we took our chances.  First, there is no sign so it takes us three passes to find the place.  We turn in; It is more like a salvage yard than campground with decrepit boats, semi tractors and travel trailers parked all about in the lawn of an abandoned house with a maybe-lived-in double-wide out back.  Yikes!   No one is answering call or text.  A good-natured fellow with jumper cables in his hands appears and we determine that yes, this is the place and there is one open site that has working power, sewer and water.   We settle in and with one final check the proprietor (at least we think he is) disappears.  We are strongly considering shortening our stay from 4 to 2 nights.  No more sightings of any management personnel and communication difficulties continue; making changes to our stay nearly impossible.  In the end we stay and pay for 3. The place served our purpose but it is the worst, maybe second worst, campground we have encountered in 11 years.
