I ran across an article talking about the shifting of Tornado Alley. This particular one is from the Weather Channel. I don't know of anyone here in Nebraska who has an actual tornado shelter. People rely on their house basements and the grace of God. My mom used to talk about the old fashioned cellars which were built separately from the house. Those would seem safer than a house basement. Supposedly, tornado shelters were popular around Oklahoma City after one of their worse tornadoes.
