Tornado shelters who's got'em and how do ya like'em? I've always wanted one but the funds have not been there. Since it's that time of year again. I've been lookin' into these things again. 1. What kind is the best? Concrete or Fiberglass. Built in or Under Ground. 2. Tell us what ya would change on the one ya have. 3.Tell us what the best features are about the one ya have. 4. Is building one yourself the best way to go? I really think having one of these is a great investment in your family's safety.
