Storm Shelters

What a strange winter we've had down here, most recently it snowed, leaving a couple inches on the ground, this hasn't happened around my ways in my life time and no-one older seemed to have experienced such an event in their life-time as well. But before that there were a couple of nearby tornado's that ripped through a few communities, which was also unheard of, maybe I should look into tornado shelters, because if this strange weather keeps up it may be nice to have one.
