Nude beach shut down, Wisconsin officials say they will close down a well-known nude beach on weekdays to reduce problems with outdoor sex and drug use. Nudists from around the country have been traveling to the beach near Mazomanie for decades, and the state Department of Natural Resources has been struggling for years to curtail sex and drug use there. Wardens arrested 26 people for illicit sex and 16 people for drugs during just nine days of surveillance in 2011. The agency announced Tuesday it will close the beach, surrounding islands and wooded areas on weekdays beginning immediately. Warden Nate Kroeplin says that's when most of the illegal activity takes place. The beach will remain open on weekends from 6 a.m. to 8 p.m.
