the name and exact location escapes me, but it was in one of those tiny, dusty Mojave Desert towns, I was the only "guest," it was maybe $15, and in the dead of winter there was no heat and no hot water. but I was exhausted and slept like the dead.
not the worst but certainly the most, um, eclectic was the former Gobbler Inn/Motel/whatever in Johnson Creek WI. red shag carpet on the walls, saggy squeaky beds, a roaring through-the-wall heater (which at least worked but sounded like a spare DC-9 engine), and a "Continental" breakfast of old doughnuts and nasty coffee. it burned down a few years ago. it was probably a fun place when new in the 60s but time was not kind to this style.
there's a Gobbler homage page
here as well. I know that Likeks twit has the definitive Gobbler site, but I can't stand him.
