What city does "Might Morphin Power Rangers" take place in?

"Mighty Morphin Power Rangers" kicked off in 1993 in Angel Grove, Calif., home to the world's most monster-prone high school and a suspiciously empty downtown. Between seasons, this supposedly modest suburb mysteriously transformed into a major metropolis packed with glass skyscrapers, perfectly matching the Japanese footage of giant monster battles the producers needed to splice in. The real estate agents of Angel Grove must have made a fortune.
