I will be honest, I didn't even know this existed. My Iowa friends took me here. It was a day that threatened of rain but luckily never happened. It's basically a park full of sculptures (duh), but they are really cool to explore. You can also follow along on an audio tour if you have your smartphone with you, and there are pamphlets that describe each sculpture. You're not supposed to touch any of them but we saw a lot of people doing that. You can make it through the whole park in about 15 minutes if you look at everything really quickly. It was a fun, leisurely stop in an otherwise busy day!
