A couple of Winters ago my wife and I were on the Oregon Coast during a big wind storm and lost power at the hotel. About 7 PM I decided to go to sleep while my wife, with flashlight in hand, read a book in bed.
11PM the "Horns and Strobe" go off.
Within a millisecond I was standing WIDE-EYED (and naked)
My wife, irritated from the disrupted from her reading, exclaiming: "What's that noise"?
