OK, I was driving down the road(fine, my friend was driving me), and suddenly, I remembered that my Gramma had wanted to check the weather for today, which I had forgotten to do, which then somehow got me to wonder, if you were driving down the freeway or something, and looked outside, and saw bad weather, and heard the tornado sirens going off, besides trying to get home, and into your basement(if you have one), or bathtub, or whatever you use, what if you didn't think it would be wise to be on the road? So, I was like, well, pull over on the side, and get in a ditch, but then I was like, hmm.....what if there were like, concrete tornado shelters for the public, built in random places, but put in the ground, like, in a slope, or a bank, or something? They could hold, like, 100-150 people. It could have a hinged door, that is easy to use, or like, a sliding steel door or something. What do you guys think? I know it is improbable, and it would be expensive to build a lot of these....but what are your opinions?
