1. They Paid Tribute to Victims of 9/11: For their first stop of the day, Prince William and Duchess Kate visited the 9/11 Memorial, where the pregnant royal left a bouquet and a note that read, "In sorrowful memory of those who died on 11th September and in admiration of the courage shown to rebuild."
