If you're planning to go canoeing on southwest Missouri's Elk River, keep your clothes on. McDonald County Commissioners have passed a law banning nudity on all county waters. Violators can be fined up to one-thousand dollars. The new ordinance passed yesterday, and officers patrolling the river will begin enforcing the law immediately. Commissioners took the action after two women were attacked over the weekend after they asked some topless canoeists to cover themselves -- because there were children nearby. The county prosecutor and the commissioners had been discussing an ordinance banning nudity on the river for several weeks. The weekend incident prompted them to take action.
