Whenever I get a break it seems our son is pretty consistent is choosing where to spend the day, The Columbus Zoo and Aquarium. I'm not sure if he enjoys the animals, rides or just hanging out more. The train ride is definitely his favorite but he could ride the antique carousel for hours.
Posing with the bronze animal statues is required on every trip, unless of course they are too hot from the summer sun.
I enjoy being able to see the animals so close, like you can almost reach out and pet them.
