Hey, that IS a good idea - know all about that wood on frozen water thing. This morning it was -18 degrees Fahrenheit! That's -27.77777777777778 celsius. I'm relieved, though, because the weather predicted -22 (maybe the cold has settled down in town, in the valley - it does that sometimes.) The ice on the window is not on the outside storm window (like in the photo). It's, now, a 1/4 inch thick on the inside of the window in our room. Brrrrrr! I'm going to go get my coffee, now. (Also, the coyotes are back and were howling in the meadow, last night, too. Outside isn't pleasant, at the mo.)
