I finally "pulled the pin". After 35 years of tornados, (one only being a block away) I bought an underground tornado shelter today. The storms on sunday and monday were it for me. Seems like they are getting more powerful every time they hit. Maybe that feeling of dread will be lifted. In any case I feel safer. As an added benefit it will be in my garage. I will now be able to get under my cars with no ramps. Pretty cool.
