Defiantly wouldn't leave unless being chased by a Kansas twister. Even then I'd go back if the vehicle survived that is.
This week marked the 29th anniversary of the Hesston tornado. I was hiding under a table at work with about 40 other people. At the 10:42 mark of video below you can see my first true love a '66 Malibu that was home at the time. Then at 10:44 you can see what was left of my Regal after being picked up smashed into a couple power poles and tossed across the street. Only 2 weeks after paying off loan, getting a new paint job, and dropping full coverage. Salvage yard didn't want any of the cars said it sucked sand and dirt into the engines of the cars. I even saw a concrete mixer truck stuck in a tree. Ran into two more tornadoes on the way home. Family slept in the basement that night. Unforgettable if you ever go through something like it.
