One way to look at today is as the first day of winter. True enough, the season of "winter" starts today. Being a glass half-full kind of guy, I like to look at today as the winter solstice, when after today, the daylight hours start increasing on the march back to warmth and summer.
Even though it's going to be cold for several more months, I take heart in the return of the sunshine.
If you're really far up north, this is what you see today, with the sun barely getting up over the horizon.
It may be the first day of winter, but don't worry: Summer is coming.
