The Green Swamp area of Brunswick County, NC is a remote area without many homes (and consequently not many lights). I visited an area of the Green swamp this morning (arrival at 4:30am). In this area, the nearest house/street light is about 4 miles away. There are still some amount of “light pollution” from the Beach areas of Brunswick County, Wilmington, NC and Myrtle Beach, SC. But it is the darkest I can find.
I found this lone tree one day while exploring.
