Some beams are almost completely covered in a spaghetti-like jumble of doodled hearts and flowers, loopy cursives and blaring capitals. Many want to simply mark their presence: "Henry Wynn/Plumbers Local (hash)1/Sheepshead Bay/Never Forget!"
Families of victims invited to go up left names and comments too, as did firefighters and police officers who were first responders. "R.I.P. Fanny Espinoza, 9-11-01" reads a typical remembrance signed by several family members of a Cantor-Fitzgerald employee.
Former Homeland Security Secretary Michael Chertoff wrote: "With you in spirit — those who perished, those who fought, those who build."
Time and daily routines have softened the communal grief as the workers carry on, trading jokes and gruff male banter. Some ends up in whimsical graffiti marking World Cup soccer matches, New York Giants Super Bowl victories and other less-weighty matters that have gone on since construction began six years ago. One crudely drawn map of the neighborhood down below shows the location of a popular strip club.
People on the ground below will never see the spontaneous private thoughts high in the Manhattan sky. The graffiti will disappear as the raw basic structure is covered with drywall, ceiling panels and paint for tenants moving into the 3 million square feet of office space by 2014.
Knowing this, workers and visitors often take photographs of special bits of graffiti, so the words will live on.
