San Francisco Cable Car Company Power Plant
Fascinating to see the one source of all the power for the cable car system that runs up and down the hills of San Francisco. Not having a tripod with me, the observation platform railings provided adequate stability to capture sharpness in a none too well lit background while preserving the motion of the ever churning wheels.
Creates a strange hunger for Rice-a-roni every time I look through the series of pics from that trip. ;-)
