The Dan Valley is an area along the North Carolina and Virginia border from the mountains to the eastern Piedmont ... from Meadows of Dan to South Boston. It is also know as the Dan River Basin. The basin includes the Dan River, the Mayo River, the Smith River and the Bannister River. When the Dan River and the Staunton River meet....They become the Roanoke River. The country side is beautiful, full of history and was settled mostly by the Scotch-Irish. Folks are friendly and hard working.
