We've lived in Des Moines 6 years and are just now getting around to visiting the zoo! At the risk of sounding like a big city snob...it was a bit underwhelming. I'm used to the Kansas City Zoo which is huge, and takes an entire day to go through. BUT, in defense of the Blank Park Zoo, it's the perfect size for toddlers. You get out of there having seen all the animals (in a couple of hours) without a cranky melt-down in the end! NICE!
Ethan loved it and we got some fun pics!
