Recently, on a solo dawdle through the Appalachian Mountains, I discovered the Flight 93 National Memorial was 45 min from my campsite at Confluence, PA... I felt compelled to visit.
I spent an afternoon at the memorial and I found it to be a very moving experience that brought back a rush of emotions. Not only is it a place of honor to the 40 courageous men and women who lost their lives on 9/11 but also a reminder of the extraordinary job our National Park Service does to showcase and preserve what it means to be an American.
