The only storm shelter with a 1,000+ year life span!
Severe weather is notoriously unpredictable. We have a vast knowledge about the conditions and suroundings that cause it and how often this occurs throughout the country. We have sophisticated warning systems, as well as extensive radio and 24/7 news and television coverage of these storms and Tornadoes as they approach and even destroy. Even with all of this technology and warning systems, still hundreds are killed each year from tornadoes, freak storms and other disasters, with thousands more injured. Property loss is routinely in the billons of dollars.
