Absolutely the derecho. I was reading this board as it was rolling along and left work early so I could go to the place where I was housesitting to bring in the deck furniture. I made it with about 10 minutes to spare so while I was both driving and on the deck I could see it coming. When it arrived conditions went from 0 to holy (expletive) in a matter of seconds. I do regret to this day that there was someone sitting outside while I was taking care of the deck furniture and I didn't yell at him to get indoors immediately.
