Oklahoma is actually pretty safe.
Plains dwellers will be happy to hear that. I drove through Windsor, CO back in 2008, not more than fifteen minutes after a twister had passed through town. I still have vivid memories of an entire freight train, laying on its side, with all the cars still in perfect alignment. On the other side of the road, was about a mile of telephone poles, snapped off at the base, and also laying in a neat alignment. Amazingly, only one death was reported.
