Smithson Grady had a large yard in the quiet town of Oakbrook, Ohio. He and his wife, Beth, were both retired. His main activities were watching sports and mowing his lawn. One Saturday, he was surprised to find a section staked off at the bottom of his back yard as though someone intended to plant a garden there, but it wasn’t Smithson. Beth didn’t know anything about it either. His back fence bordered a wooded area, and power lines for the neighborhood ran across the woods there over to the old farmhouse. Over the next three weeks, the garden area was dug up and, Smithson presumed, planted, but Smithson and Beth had no hand in it. It took a while for any plants to show, but when they did, the only thing that came up were many different kinds of mushrooms.
