Audio Story Ideas

I'm not entirely sure what I'm going to do for my audio story yet.  I've been thinking about doing a story on the Maryland Zoo in Baltimore.  It is relatively inexpensive and there is a lot to see there.  I think I'd try to speak with a zoo guide, as well as some visitors to the zoo.  Also, with the animals, there would obviously be plenty of natural sound to capture, not to mention the sounds of children in the zoo.  This is my main idea right now and I think it could make for a good story, but any suggestions would be appreciated.
