Same here. I shudder even to think of a Boston winter. My last was in 1976.
My last cold winter was in Utah in 1981...we had moved back there from AZ, and before the spring was out, we were headed south again. The next winter was in Madera Canyon, south of Tucson.
I have a heated mattress pad that I wouldn’t part with for love nor money! If you don’t have one, get one!!! MUCH better than an electric blanket!
