I lived in Minnesota from '66 to '82 and experienced many tornado warnings and sirens going off. We had several tornadoes go right through our small (20,000 people) town, and one bad one killed 4 people. We spent many hours in the SW corner of our basement waiting out the time it was was safe to go back upstairs again. Each kid had his own responsibility to perform - one grabbed a radio, one grabbed water, one grabbed blankets, one got the dogs, etc., and we headed to the basement on a moment's notice when necessary. I ran around the house, closing windows on one side of the house and opening others a couple of inches on the other side to equalize the pressure (that was "supposed" to prevent your house from totally exploding if hit by the tornado) before heading to the basement. One of the tornadoes that touched down at our little airport was less than a half mile from our house! Very scary times! Was just back there recently visiting some of the kids and grandkids, and while there, there were several nearby warnings and touchdowns! Don't miss them AT ALL!!!
