My mom and I took Huntleigh to the zoo the other day and all we did was ride the train. We didn't even see a single animal. And Huntleigh was mostly afraid of the train that day. (I think it was the little boys in front of us who screamed through the tunnels.) So, all in all, I'm not sure how "successful" of a trip it was. It's a good thing the Saint Louis Zoo is free.
