Relativity

 I just read the thermometer outside my bedroom window, and on seeing 2°, I thought, "It's really warming up!" An hour earlier, it was six degrees on the other side of zero, so I'm not wrong. Cold does challenge bike riding, but I might roll out, a little later and warmer, to ride a couple miles to a trailhead in the hope others have packed cross country ski tracks that offer more glide than I experienced in, well, a lot of untouched snow yesterday. At least I'm not having to deal with ICE!

I do want to figure out 

a thermal break for my door locks.
