This will be the shortest commuting day of the year for me, daylightwise, since I'll be off work next week when the winter solstice occurs. However, I left a little later than usual so it didn't seem any darker. I have been noticing the dark more so lately in my afternoon commutes anyway -- so much that I've been recharging my lights twice a day, at home and in the office, just to make sure they don't lose their charge.
