It’s finally become what I would call cold. When it gets down into the single digits (Fahrenheit) I’m liable to wear a sweater. So, I wore a light one for my commute. I left it on for the walk across campus to a meeting. A lot of folks are complaining about the temperature in my office building but for me, it was too warm to leave my sweater on. The car windows were all frosted this morning and a few times while stopped at traffic lights, I took pictures of the frost on the passenger side window.
