Mysterious hums: the sequel

The toadfish mating season is over and quiet has returned to Sausalito, but over at Pacific Heights and the Marina District on San Francisco Bay a new hum is driving people crazy. Speculation is rampant: Is the source a diesel generator, a hospital's portable CAT-scan machine, or underground electrical power lines ? We'll just have to await more communications from California. (Rubenstein, Steve; "Detours on the Trail of Mysterious Hum," San Francisco Chronicle, September 25, 1985. Cr. P. Bartindale)
