It's that marvelous, magical day where the time of sunshine and dark are equal, no matter where you are on the planet.
Spring Equinox for those of us in the Northern Hemisphere. Fall Equinox for those of us in the Southern Hemisphere.
For me, just a couple of weeks ago, it was snowing. Today, the sky is clear blue and sunshine warms the air. I'm thinking of what I'll be soon planting.
