It was in Funtier Town
LOL, it wasn't so much strange as it was memorable.
It was around 1970, and I was visiting SF. I took the streetcar out to Playland, which was in the process of being shut down, or close to it. I remember walking past one of the buildings, and there was an open crude wooden door in the side of a crude wooden building painted a sort of odd blue/green/gray. I think it was attached to some sort of Wild West attraction called "Funtier Town". Inside there was a white automatic washer chugging away. No, I don't remember the brand. I remember looking at this prosaic evidence of domestic life, and how out of place it seemed in an arena dedicated to, well, fantasy. As I gazed curiously an unseen hand swiftly shoved the door closed. Not slamming it, but close to it.
I suppose it was a caretaker's residence, probably in the last year of residence, and not appreciative of my prying eye. Nowadays the site is all apartments and condos. No more narrow gauge roller coaster (it was REALLY small) or whirly rides. No more laughing Sal in the Fun House. And no more old washers chugging away behind the rough hewn doors of Funtier Town.
