What do you do, first?

The last thing I'd do is show any lights. I'd look out the window to check if the whole town was out, try the land-line phone to the fire department dispatch to see what was going on. If land-line was out (this would be a big deal since land-line phone have a completely separate power grid) then flip on the SW to copy US traffic. If outages are being widely reported, deploy the WaterBobs in the bath tubs, notify the next-door neighbor (who would notify his next-door neighbor and so on), lock and load, and await daylight.

Sorry River Song, but the wife and I are too old for "panic sex"!
