These days there is no safe zone I'm afraid. I grew up with bomb shelters and storm shelters. I refuse to be buried after I die. Spent way too much time underground since my mom and grandmother were terrified of tornadoes. A single drop of rain and we ran to the storm shelters. The only tornado I was ever in, I slept through. It came right over our apt. The back door started shaking like someone was trying to force their way in. I was surprised when I went outside and saw bits of roof and tree limbs all over the place.
