Two years ago, one of the worst tornadoes on record hit the town of Moore, Okla. And you might say to yourself, well, doesn't this always happen there? It's called Tornado Alley for a reason.
And that's pretty much how the residents of Moore think about tornadoes. They're just part of life, and you take your chances. But that kind of thinking was part of the problem on May 20, 2013. The storm that came through that day was different. It was horrific.
