I live in Northern Nevada. The typical house of prostitution consists of several older double-wide trailers, surrounded be a chain-link fence topped with razor wire. It's is an area of wrecking yards, porno shops, crack houses and beer bars. And the men going in and out of these establishment tend to be the pitiful wrecks of our society. These places will never be mistaken for resort hotels, dude ranches or even 1950's Los Vegas style strip motels.
Also I question the amount of money these sex workers say they have earned, considering their typical clientele (callow youths, handicapped adults, and the elderly).
Yes, some better paying clientele from out-of-state, travel from the nearby hotels to be serviced. And places such as the Moonlite Bunny Ranch, and the Mustang Ranch provide limousines for their better paying customers.
