Long gone are those days, I visited the Cliff house museum as a child in the late 50's only to return in the 70's to find it all gone. It had a history of burning down but was always rebuilt. The arcade is on a pier in Fisherman's Wharf, the mummies are in collections and the bed, clothes and artifacts of Tom Thumb and his wife are who knows where. It made a lifetime impression on me.
The Pike in Long Beach is long gone to as are other places of public history.
