Brisk

I just got back from a not-quite-a-mile walk from the house where I was dog-sitting last night to my apartment. That was after a walk of about the same distance with Becky, the dog. It's a beautiful day - clear blue sky, the sun casting shadows of tree branches across the shining snow. This is the sort of winter day I like, though I felt a bit cold. And then when I got back to my apartment I found the temperature was -6 with a windchill of -18. Oh. That's why.
