Are you telling me that some people go to the National Zoo for purposes other than seeing the giant pandas!?The first time I went to the Smithsonian National Zoo was almost solely for the elephants.
In all seriousness, the first of my two visits to the National Zoo was on a school trip that allowed one hour for the zoo. My priorities were Clouded Leopard and Black-footed Ferret. I managed to see the Asia Trail, Elephants, Small Mammal House, Reptile House, Lemur Island, and Cheetah Area at the fast pace of animal, sign, picture, next.
