I don't know where you live in Tenn.,but here in the west we get them pretty often. Two years ago we had a killer tornado in Covington.
Chattanooga. We had one touch down several years ago. The last one previous to that had been 50 years or something. I discovered that my children did not have the first clue about how to seek shelter in a tornado.
My sister lives in the Memphis area, apparently tornados are fairly common there.
