I'm saving up to go to the zoo. In the meantime, I've been listening to these. They really explain the animals, and their habitats. The Panda ones are especially good, because they talk about Su-Lin, the newest panda baby I've gotten to know since her birth on the panda cam. My only problem with these is perhaps they should have been merged to one podcast for each animal instead of several, so I don't have to keep moving my click wheel when I am listening on my ipod.
