31F at 5:30AM today when I went down by the lake with my dogs. There was a heavy layer of frost on our deck with some ice on the driveway so I decided to be cautious & drove in. Two colleagues rode in without any problems though and when I went home for lunch, it was a balmy 36F so I put on my heaviest wool sweater with a wool band to warm my ears & put my booties on. Had a comfortable afternoon commute & I was able to put a few more miles on my new bike. Supposed to begin raining tonight so it will be warmer tomorrow. Don
