@DavidBrown I think it's a fantastic zoo, and I don't understand all of the hate that it gets (other than most of it is from peta fans). Most of the exhibits that people think are too small are that way because the animal(s) they hold have injuries that limit their movement. The only exhibit I wish was bigger is the cougar one, but it's not as small as it appears. The entire staff is very dedicated and put up with a lot of nonsense from the public, more than their counterparts at most other zoos because of the free admission to those visiting the theme park. They are very dedicated to native species and have some of the best vet care in the country thanks to their on-site building and proximity to UPenn vet schools.
