Found this interesting video featuring several abandoned zoos. There are a couple of errors where the visuals do not match the narration, the most notable is at the very end when they are discussing Griffith Park Zoo and throw in a photo from several segments earlier of Stanley Park Zoo. Still it is an interesting watch nonetheless (and I have been to two of them myself, Two Guns and Griffith Park, though they do not feature a third I have been to at Crandon Park).
