An online Santa tracker run by a Canadian and American defense agency mapped the jolly old gift-giver's path around the globe Saturday, in what has become a Yuletide tradition. Every Christmas Eve since 1955, the North American Aerospace Defense Command (NORAD) has been tracking Saint Nicholas's annual voyage to deliver presents to good little boys and girls around the world. A 3-D, interactive website at www.noradsanta.org shows places Santa has passed through, allowing site users to click to learn more about different locations.
