Spent the week before Father's Day weekend with my Daughter hiking the Appalachian Trail from Front Royal to Harpers Ferry. ATC HQ is a mandatory stop for all of us who hike the trail as the "unofficial" halfway point. It allows hikers to see old friends we have missed on the trail. As soon as you walk thru the door, the staff instruct you where the water or Gatoraide is and get you ready for your famous picture, the one in front of the ATC sign. Of the hundreds of pics and memories you take on the Trail, three are the most important: at Springer Mountain; at Katahdin Mountain and at ATC HQ. The museum is a great display of our country's greatest hiking trail.
