There are two more in the house, plus a few empty ones in the basement. If the power goes out we start filling jugs until we drain the pipes. With judicious use, that's a few days of washing up and flushing toilets. Ah, sweet civilization! In the summer, when a horse might drink 5 gallons of water a day, that's barely enough for one day, and forget the washing up.
Power outages also mean no computer, which means I am reduced to writing the old fashioned way with a pen and paper - in my opinion, one step above a stone tablet and chisel. To be prepared I usually print out the last 2 or 3 pages of my work in progress before the storm hits. That way I can review and edit, which helps me slip back into the story. My output suffers, but it's better than nothing. I'm hoping that doesn't happen with this storm, but with a foot of snow pulling down tree limbs and power lines, I can't count on it.
So... Water bottles are full. Pages are printed. Warp speed, Mr. Sulu, and keep those engines running, Scotty!
