Staying warm when it's cold

It was -20F this am. I have both woodstoves going, and it's a balmy 85 inside. The generator wouldn't even turn over this morning, but there was enough juice in the batteries to keep us going all last night and today. Finally got the generator fired up about 9pm so Linda could get the laundry done. I'm on call for the Hospital, but I'm hoping it's a quiet night. We have about 6" of new snow in the last few days. Not enough to make life difficult.
