Just think of how much time, effort and money it took to create such wonderful pathways, as the sculpted riverbank edges alongside the lush undergrowth shows the attention to detail that makes San Diego such a wonderful establishment. Not only are the exhibits mainly excellent at this all-day zoo, but other factors (pathways, climate, food, gift shops) are brilliant for visitors.
Interesting comparison between the aesthetic present at the onset of the bioclimatic plan with the current aesthetic. (Photo from ZooChat by Arizona Docent)
