Posada Christmas Pilgrimage Reunites Family, Friends at U.S.-Mexico Border

There's a Mexican Christmas tradition called a Posada that usually involves a festive street procession re-enacting Mary and Joseph's search for shelter. But the celebration takes on a different form at the southern tip of San Diego County along the U.S.-Mexico border. Under the watchful of eye of the U.S. Border Patrol, people on both sides of the reinforced security fence meet to sing carols, share news and hold tearful reunions.
