season for stuff like this to happen in the city. now, moore was hit three times. we had a '99 storm, a 2003 storm and now a 2013 storm. all of those produced damage. about 200 miles per hour. the f-5 number, that means the entire house is gone. all that's left is foundation or the slab that's on the ground. all the wood, all the insides, refrigerator moved away from the house. it's gone. it doesn't happen often, but it happens once in a while. towns do get in the way. >> yeah, we saw the aftermath of that. we're looking at live tower cam pictures. our h. chad myers, i know you're storm chasing. please stay safe down there, thanks so much, tom saider, as well. now, to a late, new development in the investigation of the threatening letter sent to president obama.
