So I did manage go get out for that walk today. It was sunny and warm, but the sun is so low that the trees cast long shadows. The sidewalks were very icy and slippery in places. I'd hate to live here as an old person (comments that it is too late to start worrying about that will not be gratefully received).
Did some exercise yesterday, and I'm stiff and sore today. I expect I'll survive, though.
