A noise you don't want to hear

While living in Kentucky, the threat of tornados were thrilling, but also horrifying. When the sirens went off, to the basement you go. I have vivid memories of one spring in particular where I spent a lot of evenings in the basement...just in case. I post this because I've had tornado dreams the last few nights and, while scanning the weather channel, I realized that tornado season is upon the nation once again. If you hear this sound. Take cover. It's for you own good.
