Congratulations
@Neil chace on your bravery with your orangutan selections!

This is a great thread so far, but unfortunately the great red ape choices are a little perplexing to many of us. We praise your nice work, but you also have to occasionally deal with some criticism. Saint Louis, Woodland Park and Atlanta are wonderful selections, Indianapolis I haven't seen but I understand your point with including it...but Cleveland? I would put Cleveland in the 5 worst orangutan exhibits I've ever seen because I truly struggle with that all-indoor enclosure. I find it to be very small, with an ugly fake tree, and I have never been a fan whatsoever.
I would have chosen Omaha as the replacement, although now that exhibit is closed and being revamped and modernized.
So, here's another option. It's essentially a big cage, but Fresno Chaffee Zoo renovated its orangutan exhibit and it just reopened in the past month. Many more ropes were added, as well as a huge fake tree with areas for obtaining food or allowing the apes to sit in front of the viewing window. There are 4 Siamangs as well, which creates a terrific dynamic. I don't know if it's top 5 material, but it's a million times better than the junky enclosure in Cleveland.
These photos are hot off the press as I was just at Fresno on Friday.
I know that when I was touring European zoos on my past two road trips, I was told that a way to get orangutans off the ground and up into the canopy part of their enclosure is to have mixed-species exhibits. I saw orangutans with Malayan Tapirs, Small-clawed Otters (which can be feisty little critters) and Binturongs (admittedly an arboreal species) and having tapirs and otters on the ground quite often forced the orangutans to a higher area. Alas, if only North American zoos would get on board with the creation of exciting mixed-species exhibits involving apes...
