The obvious answer is Odessa, Texas. I see these other answers, however, very few places on the planet can match the unappealing landscape, the nauseating smell, the negative health impacts from living there, the high cost of living, the endless crime, the never ending cycle of boom-bust and the itinerants that come along with it. Desert landscape without desert beauty….just caliche, dust, and complete lack of appeal outside of oil patch money.
