My heart goes out to the many families whose lives were literally turned upside down in Oklahoma recently, when tornadoes took lives, injured many, and destroyed homes and businesses beyond recognition. But when you live in an area that's prone to tornadoes, you would think that a tornado shelter would be a common item--apparently they are not--but they should be.

Are the shelters cost prohibitive? Probably so. But there should be shelters around strategic points with signage pointing to there whereabouts, much like bomb shelters.

Here's a story of a shelter that saved 11 people when the EF5 tornado ripped through Moore, Oklahoma. It was installed after a 1999 tornado hit the same city.
