Abandoned factory (San Francisco)
The Washington Packing Corporation was a tuna canning factory and operated in the early 1960's, until botulism killed several people who ate tuna canned in this factory.
The people who have been there noticed that this wheel spins continuously with the power of the wind in the airduct.
