Original location was on Peri Ranch Road, about a mile east of Lockwood, NV, along the Truckee River. The abandoned structure appears at 0:35 and 0:58 in this video by roobyroo2000. Even today, the place is vistited by the Virginia Range mustangs.
Current location of the brothel is a few miles to the east, at the Tahoe Reno Industrial Center, also inhabited by the Virginia Range mustangs.
Interesting bit of history but the activities that occur there are damnable.
