Members of the George Washington's Young Friends, playing traditional music, will greet holiday guests in the Visitor Center, introducing them to another world--the world of December 10, 1774. Guests will hear the sounds of revelry, drumming and rifle shots heralding the season. Wood-burning flambeaux will illuminate the landscape, adding their light to dozens of candle lanterns guiding the way to the Great House. Don't be surprised to encounter personages from another era who will gladly discuss any subject of the day. Inside the Great House, music will fill the air. Admission: $10 adults; $5 for children under 12. No discount for FOS cardholders for this event. The renowned Washington's Camerata, a period instrument ensemble, will perform two concerts in the Hall, one at 5:30-6:15 p.m. and a second at 6:45-7:30 p.m.
