I've been in one tornado--with a very similar experience. The tornado touched down at the crest of the hill and we were about 100 ft. south (on the road). The very old farmhouse we were living in had its windows sucked out on one side, the square nails were pulled out from the boards, the linoleum was sucked up about two feet, it split a huge oak tree in the front yard, missing my car by about >.< much...but it's the sound I'll never forget. Never. That roar....I've been near a couple others, even saw a few form, but that's one experience I never want to repeat. I feel so much sympathy for those going through these tornados.
