Ok, not by the calendar. But there's always that first day where you can feel for the first time that spring is much closer than winter. The air, only warmish, smells like spring. On Canada Pond, the swan starts chasing the geese in earnest. I wonder if this year there will be cygnets.

3-6 inches of snow tomorrow, followed by three days of precipitation of various kinds. It's not spring. But it's close.
