arboreal

Which zoos and which species have crossings over visitor paths, so that animals, e.g. monkeys, orangutans or binturongs walk over visitors heads? Especially interesting are open ones (not closed passages) where an animal could theoretically jump down. How high are those approximately?

My name is Ron, I'm new to this scene and would like to get involved in zoo exhibit work......thought this could be a good place to start. I specialize is custom made, hand sculpted epoxy inserts for arboreal snakes. But this type of exhibit work can fit into any reptile or amphibian...
