Why December 22nd? Because it's the winter solstice. From that day on the days start getting longer. One of the draw backs of living so far North is that it gets dark so early in the evening and takes so long to get light in the morning. I took these two pictures on the way to work yesterday morning.
By the time I was headed home it was much darker then this. And people wonder why I insist on leaving the office at lunch. If I didn't, I'd NEVER see the sun. (Not that I can see it now thanks to the cloud cover but at least I get some natural daylight).
