Family members and friends of the state's 9/11 victims gathered at Liberty State Park in Jersey City to open the Empty Sky Memorial. Among the crowds who turned out for the event were five former governors, the state's two senators, and members of the military. The names of 746 New Jerseyans who died on Sept. 11, 2001 line two reflective walls of the memorial. The walls, which rise some 30 feet high, are oriented to follow a straight trajectory to where the Twin Towers once stood. With a light rain falling after the ceremony, family members waited in long lines to walk through the memorial and were given a chance to make an imprint of the name of their loved one.
