Skip the mall and have a BLAST at Fort Mifflin the day after Thanksgiving! Spend the day exploring one of the only intact battlefields from the American Revolution and enjoy musket and cannon demonstrations! No long lines, no grumpy shoppers. Give thanks for the soldiers that fought here, allowing General Washington time to establish winter quarters in Valley Forge in 1777. Guided tours at NOON and 2 PM. Musket and cannon demonstrations ongoing.
