This is one of the coolest places in our city. It's an old (10 story?) warehouse or something that has been changed into a huge children's (and adult's) museum. It's made up of amazing climbing structures that take you from floor to floor, giant slides that take you many stories down, one even goes from the top to the bottom in a winding slide, a circus performed by local kids who learn at the circus school there, and many other super cool things. You could spend a couple days there and probably not see everything.
We went with our new friend, Bella. She is the niece of a co-worker of Richard's. She spent a few days hanging out with us this summer because her aunt thought it would be more fun to play with us than sit at the office while she worked all day. She was right. We had fun with her.
