Just for fun I've been monkeying around with my own "Master Plan" for future development of the Tulsa Zoo (my "home" zoo). I'd posted it previously but have continued to make changes, so thought I would post the latest version for any comments/criticisms/etc. I have no official relationship with the zoo, so this in only my thinking about where it could go, based on reasonable changes and additions to its current collections and layout. I'm posting my "Master Plan Map" and the written explanation, as well as the current zoo map for reference. Let me know what you think!
And here's the actual current Tulsa Zoo map for reference (which is actually out-of-date, since the Events Lodge has been constructed and the Sea Lion Cove is currently under construction after much delay).
A more ambitious plan I've continued to refine my first plans into something more ambitious, and mapped it out using actual satellite photos of the existing zoo. Here's the newer plan and explanation.
