Prostitution has been banned at Mustang Ranch, America's best-known legal brothel, by county officials who are tired of its notoriety.

The prohibition leaves no room for the Internal Revenue Service to sell the 105-room, 440-acre ranch as a working bordello when it goes up for auction to pay the longtime owners' tax debt, estimated at $13 million.The Storey County Commission decided Tuesday to make prostitution illegal in the area of the county where the Mustang is located, leaving in the clear a nearby brothel.

Commissioners stressed they remain in favor of legal prostitution in Nevada, but rezoned the Mustang because of the "circus" surrounding it for 35 years.
