The link above is from the tornado damage that destroyed 1/2 the town of Parkersbug, Iowa (5 miles from my home town of Aplington, and 25 miles from where I live now). 1/2 the photos were taken just 2 hours after the tornado, the rest were taken the next day.
I was in town working on repairing the fiber CATV fiber optic that fed several towns west of Parkersburg (yes I am a cable guy).
It is a utter miracle that anyone survived that F5 monster!
