People wave as Pope Francis arrives to celebrate the World Youth Day's final Mass on the Copacabana beachfront, as Brazilian Navy frigate ships navigate off the shore in Rio de Janeiro, Brazil, Sunday, July 28, 2013. Many of the youngsters on hand for the Mass spent the night on the beach, an all-night slumber party to end the Catholic youth fest, with pilgrims wrapped in flags and sleeping bags to ward off the cold.
