People carrying cameras, dogs and children lined the streets along the road as the president, first lady and their daughters came to the island of Oahu for a more-than-weeklong vacation yesterday. A crowd of about 75 military servicemen and women and Hawaii politicians greeted Air Force One when it landed at Hickam Air Force Base. Obama took several minutes to greet military personnel and their families before getting in a black SUV for the ride to his vacation home. The Obamas have no public schedule and are expected to celebrate the holidays in private at a rented compound in Kailua. (More Barack Obama stories.)
