The Cincinnati Zoo was our absolute last stop on our vacation (well other than a stop for gas probably). We love zoos, but by this point we were feeling pretty tired from the long trip on the road.
It didn't help that, even with my eyes constantly glued to the park map, the layout was terribly confusing and we kept getting lost.
The coolest part was the cheetah running demonstration. You went to another arena area and they had this pulley system rigged up that yanked a toy for a long distance to get the cheetahs up to top running speed! It was really amazing to be able to see that in person.
