Last fall I found this gem of a county park tucked away in eastern North Carolina. They don't accept reservations. We arrived to find the campground had no room left. They offered us overflow camping at the same price. Usually overflow camping has no electric or water, but they told us there was an electric post we could use if we parked near it.
To our surprise it came with two dozen 30 amp outlets. The circus could come to town and plug in!
One other RV was in the overflow lot, he had the only water hooked up to his rig. We asked him if we could fit our Y-valve on the spigot and share his water. He was quite friendly and readily agreed.
The campground proper is shown in the rear. I loved this little park and would gladly visit there again. Maybe next time I can snag a place inside the campground.
