May Day, usually celebrated on the first day of May, is an ancient northern hemisphere spring festival. For a May Day bash at the William Paca House, we’ll first listen to Little Gray Rabbit’s May Day, and then we’ll do crafts and other activities to jubilantly celebrate the spring. 10:00-11:15 a.m. Reservations required. Cost: $8 per child for HA Members and Volunteers, $10 per child for Non-Members
