Right, and for example LA is actually full of concealed oil wells pumping oil in the middle of the city (!). https://www.noemamag.com/its-oil-that-makes-la-boil/ https://www.noemamag.com/its-oil-that-makes-la-boil/ > Fifty-four tightly clustered, slanted oil wells — the last of the Salt Lake Oil Field — sit snuggly between Macy’s, Bloomingdale’s and San Vicente Boulevard. In fact, the Beverly Center’s odd, curved footprint is designed to accommodate the drilling site, which is hidden by a wall along the street. The wells are almost completely invisible, dwarfed by the mammoth mall and the sprawling Cedars-Sinai Medical Center across the street — the hospital where I was born and where I later dropped my friend off to meet his wife for an ultrasound appointment.
