Children of all ages are invited to join the garden club, Harpswell Historical Society and the Harpswell Community Theater for skits, carols, cocoa and cookies at Centennial Hall as we turn on the lights to the town's tree. This year's celebration features skits produced by the Harpswell Community Theater at 4:00 p.m. There will be an intermission after the skits for refreshments and conversation. Finally, we move outside for more carols and the tree will light promptly at 5:30 p.m. Centennial Hall is located at 936 Harpswell Neck Road (Rt 123) in Harpswell.
