SHELTER

In 2005 my mother and I moved into a mobile home. If a tornado bore down on us and we didn’t have time to vacate, our options were few. One was to lie in a ditch with hands over our heads. I thought we could do better than that. So I had a pit dug and dropped in two trash cans. In 2011 a video showing the tornado shelter was put on YouTube.
The trash can tornado shelter has flaws, but it beats lying in a ditch. I hoped people would take the idea in the video and improve on it. See what you can come up with.
