Pilgrims carry the World Youth Day Cross through a Sydney street after it arrived by ferry at Circular Quay, Australia, today. Pope Benedict XVI will attend the event with thousands of pilgrims from around the globe. Benedict, 81, arrived in Sydney on Sunday but was resting from the long flight before joining the festivities on Thursday. World Youth Day, which begins Tuesday and runs through Sunday, is the largest public event in Australia since the 2000 Olympic Games. At today's procession, groups of volunteers took turns carrying the 88-pound cross along one of Sydney's main streets.
