The Memphis Zoo, rated top zoo in the country in 2009 has two bicycle racks each capable of handling eighteen bikes, but the positioning of each limits the number to 9. With the parking situation in shambles at the Zoo, I'm surprised they haven't given discounts for people who ride a bike or walk. But then, they do charge for car parking.
With all of that money they're raking in it would be cool to see some animal shaped racks like the large sculptures gracing the courtyard.
Here's how the racks rack up:
Form - Utilitarian
Function - Another Half-Pass
Environment - Donate these to someone and get some animals out there
