More than a decade after 9/11, no one's quite sure what to call the spot that was once a smoldering graveyard but is now the site of the fast-rising, 1,776-foot skyscraper that will replace the twin towers. Some are calling the new skyscraper "One World Trade Center," but it's still "ground zero" to others. (AP Photo/Mark Lennihan, File)
