When we went to the zoo (late 1960s and early 1970s) we barely got past the first section at the old entrance: the Mother's Building, the playground, Storyland... Give me a brick of pink popcorn and I was happy for the rest of the foggy day. It's a wonder I ever got to the manure-throwing chimpanzees.
Any memories of the Zoo playground/locomotive/cable car? I'm sure some train buffs here can tell me where these old rail relics are now. (The SP locomotive is numbered 1294. I can't see any numbers on the cable car...)
