Activists are asking a federal judge to block a city ordinance banning public nudity. The ban is scheduled to go into effect Feb. 1. The local law has become a divisive political issue in a town that prides itself on its inhibitions. The demonstration took place before a court hearing on the ordinance. (AP Photo/Eric Risberg)
