We drove to St. Lous on Sunday morning to stay in a hotel for the night and head to the St. Louis Zoo on Monday. We kept the zoo a surprise from Parker until we walked up to the gate that morning. Parker was thrilled to see all of the animals! He especially loved the exhibit called "DinoRaurus." There were 16 life sized mechanical dinosaurs that spit, moved and made noises. They were really cool. We walked around that special part of the zoo at least 3 times...........we probably could have stayed there all day and Parker would have had a great time.:) We stayed there for about 5 1/2 hours without any meltdowns or complaining. Unfortunately one thing that I fogot to do was charge my camera battery:( It died after about an hour into the zoo...........:( I didn't get any pics with the big animals......oh-well, next time.
