One-room hut housing a family of nine built on the chassis of an abandoned Ford in a field between Camden and Bruceton, Tennessee, near the river. March 1936. View full size. Photograph by Carl Mydans.
Caption card says "on U.S. Route 70 between Camden and Bruceton, Tennessee, near Tennessee River. Their water supply was an open creek running near state highway."
I am from this area and I can not think of any river around the Camden/Bruceton area. If you are referring to the Tennessee river, that is about 8-12 mile, depending upon what shortcuts you know.
This was an interesting thing to have stumbled upon. Thank you for the picture.
