Join us to celebrate the first day of spring and the last full moon of the winter season! Two seasons intersect on this special day when frogs will be singing while winter is still holding onto the air and earth. The March full moon is often called the Sap Moon by Native Americans; this time of year heralds the sugaring season when sap begins to flow in maple trees and the ground softens enough for earthworms to reappear, inviting the return of robins.
