I've gotta say if you've never been to the Columbus zoo, you really should go sometime. It's one of the better zoos I've been to---Jack Hannah's home zoo---and they've added on some excellent exhibits in the last five years or so. They have a brand new, amazing Southeastern Asia section... and I love their North American section, as well. Definitely recommended!

Looks like my next visit to the C-bus is going to include a swing by the zoo...
