"The crisp new signs began going up in some of the most popular spots in Central Park near the end of May. In large white letters on green backgrounds they announce that the areas have been designated Quiet Zones, and that musical instruments and amplified sound are not permitted. Some of the signs cite the authority of the Central Park Conservancy, the private organization that manages the park. Others also bear the name of the city’s Department of Parks and Recreation."
