-4F when I left this morning. I stopped at the convenience store by my home to fill my thermos with coffee and took some home for my wife. I was planning to leave for work after that but after 10 minutes my hands were already cold, and the tears were freezing my eyes closed. So I got a ride. We still need to get goggles and ski mittens or something similar before we're ready for temps quite this cold. Otherwise I feel like I'd have been OK.

I won't be able to get goggles until next week so I'll say this is it for 2017. I would guess I did around 2,500 total commuting miles this year, starting the first week in September.
