When the TVA brought electricity to rural Mississippi
One of my favorite stories, told to me by a tree surgeon:
His uncle lived on a farm in Mississippi during the Great Depression of the 1930's. He had no indoor plumbing and no electricity. He got up when the sun rose and went to bed when it set. One day a man from the Tennessee Valley Authority came and talked him into letting them run electricity to his house. They ran the wires and hung one bare lightbulb. A while later his uncle got a bill for about a dollar. He was furious and asked them to take down the wires to his house. He went back to going to bed and getting up with the sun.
I imagine the uncle's house may look something like this today.
