This is a really tough choice. I’ve lived in Arvada, Colorado for my whole life, and I’ve been to Denver Zoo about 50 times (camps included), Cheyenne Mountain about 6, The Aquarium probably about 20, The Butterfly Pavilion about 15 times, and the Wolf Sanctuary Twice, I’ve never been to Pueblo. For me the vote is between Denver and Cheyenne Mountain. The one issue I see in the vote is that Cheyenne Mountain is finishing their master plan while Denver is just beginning theirs. However, I think because of things such as Tropical Discovery, Toyota Elephant Passage, and Primate Panorama, I’ll have to go with Denver, just barely though. (Perhaps there is a bit of a personal bias here though lol).
