Last Tuesday, Lori Mehmen, who lives in Iowa, Orchard, looked out from behind the front door of her house and that's what she saw. She had a digital camera at hand, and somehow she managed to take this picture, even before she was terrified. That is why, dear readers, it is so useful to have a camera on hand. Incidentally, in this tornado, fortunately, no one was hurt.
