(Fort Mifflin, and for the Google Earth fans, 39° 52' 31.32" N, 75° 12' 47.25" W. ) You will learn to fire a matchlock, crew and fire a cannon, handle a pike (it's not just a pointy stick), and swing a sword (with blunts, of course).

Period food is provided, $30 USD USD   for pre-registration for the weekend, including meals.  One day is  $20 USD USD , which includes lunch.
