Nope, not thunder. Camp Lejeune is 15 miles away; the rumble of artillery fire travels quite well. Compared to traffic, airplanes, and trains at RV parks we have camped in, this is easily ignored. This is actually a lovely National Forest campground among tall lollaboly pines along the White Oak River. It is just 3 miles from the Atlantic coast too. We will spend a few days checking it out.
