You know when old age is dropping the hammer on you, when 40 degrees feels cold! man I was born in Minn, spent a great deal of time bucking snow drifts on the divide in wyoming. You'd think I could handle some cold.
Lesson learned. A heat pump is not the way to go in Oregon. temps hitv40 or lower, and you are screwed.
I wish I had a good old wood burning stove right now. As for Al Gore. I'll send him an invitation to head up the Dinwoody glaciers with me in wyoming next summer. Gee Al,, they're doing well here?
