The cellphone service along Nevada state Route 160 starts getting spotty about 30 miles outside of Las Vegas. Calls drop mid-sentence, if they connect at all. The radio cuts out just past Mountain Springs. GPS endlessly recalculates. By the time you get to the turnoff for Dennis Hof's Love Ranch, a legal brothel on the outskirts of the outskirts of Pahrump, the only calls heard clearly are coyotes howling across the Amargosa Valley.
