The Star-Ledger took a cross-country trip to tell the story of Americans' longing to connect with this nation's great tragedies -- to touch hallowed ground -- at the anniversary of 9-11. We started at Ground Zero and we kept going, visiting the country's most wounded places: Gettysburg because Americans continue to grieve about a war that began 150 years ago and because Gettysburg, over three days in July 1863, was the scene of the greatest loss of life on American soil; Arlington National Cemetery our most sacred burial ground; Oklahoma City, site of the first major terrorist attack on U.S. soil; and Pearl Harbor, site of the first foreign attack on U.S. soil and the highest loss of life from a foreign attack -- until 9/11.
