 Since the 13th century, sheepherders in Spain have had the right (still honored) to use 78,000 miles of paths in the country for seasonal flock migrations -- even some streets of Madrid, including a crossing of Puerta del Sol, described as Madrid's Times Square. The shepherds pay a customary, token duty, which, according to an October Associated Press dispatch, the government proudly accepts, given the prominence of Spain's native Merino sheep breed in the world's wool market.
