Jeanmarie Hargrave corralled a group of tourists from Atlanta who were taking photos of the miraculous Callery pear, a living tree that was found broken in the smoky ruins of Ground Zero and slowly nursed to health.
Ms. Hargrave, 64 years old, is a docent with the 9/11 Tribute Museum in lower Manhattan. “My brother T.J. worked on the 105th floor,” she told the group. They looked up to where the Twin Towers had stood 20 years earlier. It was a city unto itself, she said. After the attacks, new skyscrapers were built on and around the 16-acre World Trade Center site, including the tallest in North America—One World Trade Center, reaching 1,776 feet and marking the intersection of the Hudson River and New York Harbor.
