The best harbinger of spring (in my opinion) is the earthworm. They are out in full force today, making it difficult to walk down the driveway without stepping on them.
This happens every year about this time when the snow melts and the earth thaws. They must wake up from a long winter of hibernation, ready to let the light hit their translucent pink bodies.
There is not a lot of light today as it rains lightly. But the earthworms seem to be as anxious for spring as the rest of us are.
