The Henry Knox Museum will launch a new community event called Knoxfest Saturday, Aug. 10, beginning 5 p.m. on the south lawn of Montpelier, the big white house at the Route 131 turn to St. George. There will be food and music and games and a giant make-your-own-sundae dessert bar, followed by the screening of an action-packed outdoor PG-13 movie featuring Henry Knox. Admission is free and all are invited to attend.

Everyone is invited to bring their dancing shoes or just a blanket or lawn chair to kick back and enjoy the summer evening. At 5 p.m., the popular Midcoast steel drum band Steelin’ Thunder, under the direction of Mike Miller, will begin its three-hour set. Lawn games, including a major community tug-of-war, will be available. Museum board member Bradley Boyd will be firing his signal cannon and showing folks around Hope, the museum’s cannon that sits on the front lawn of Montpelier. Information will be available about the Paul Revere-made bell that also sits on Montpelier’s lawn.

Thomaston’s Pete Lammert will fire up the grill and serve his famous barbeque chicken dinner between 6 and 6:30 p.m. At 7 p.m., giant tubs of ice cream, hot fudge and all the fixings will come out for a good old fashioned ice cream social. At 8 p.m., just as the sun goes down, museum friends from Camden Public Library will roll out the big screen and projector used use to show movies in the Camden Amphitheatre to screen the educational and entertaining PG-13 movie “The Crossing,” about George Washington and Thomaston’s own Henry Knox crossing the Delaware on Christmas Eve in 1776 to fight and win the Battle of Trenton, a victory that would go down in history as a major turning point in the American Revolution.

Montpelier is open for tours Thursdays and Fridays from 10 a.m. to 4 p.m. and on special event days including the Saturday of Knoxfest, on which tours will be available and The General’s Store will be open from 10 a.m. to 4 p.m.

Moviegoers are asked to bring blankets or outdoor chairs, if possible. Some seating and a tent will be provided, so the event will go on rain or shine. Knoxfest is the fourth in a series of community events held at Montpelier this summer, kicked off with the second annual Boots on the Ground Memorial Day weekend, and continued in June with Midsummer at the Museum; and in July with Cut the Cake! Next up is Taste of Thomaston, a food, wine and practical know-how celebration on Columbus Day weekend. For more information, call 354-8062 or email info@knoxmuseum.org.
