FAO Tornado-Fearing, Black-and-white thinkers.

Running from a tornado is typically easy. Heck, some people even chase them around for a living.

Only issue would be traffic. Surprisingly, all the ones I have seen (lots, grew up in Wichita Falls, TX) visibility was not that much of an issue. We just go out back and watch them. Most never made it 100% of the way to the ground. Some did.

And yes, F5's are 'foundation polishers'. ...there will be nothing left above ground except bank vaults.
