I would not be happy if I was having heat/pipes/car problems in this weather, as the weather itself can cause enough stress. Spending the $ for new insulation, roof, windows, and doors has made my house so tight that nothing escapes, so I don't feel so bad now about all the work we had to do, despite how I felt while we were doing it.
Yesterday it got up to 21 and it felt "warm." Today, I just finished my workout on the trainer, as the high is going to be around 16 and there's not enough snow for snow shoeing. Local hiking wouldn't warm me up enough! Tomorrow is going to be around 30, with snow showers, so I will definitely do something outside. But then, we are plunging back into the deep freeze for about a week. Some little snows forecast, but now I am obsessing about there not being any snow in Stowe, VT for my x country ski trip.
