When you live in the city in a 2 BR condo, free space is at a premium. We've often found ourselves wishing we had a basement, a backyard, just some place where the kids could run around and we wild for a bit. Last weekend, we found our equivalent of the "urban basement" at the Chicago Children's Museum. This place is fantastic. They have an entire room dedicated to building forts...perfect! To make it even better, Auntie Laura, the absolute queen of fort building, was in town to join us for the fun. We promptly purchased season passes and plan to be back quite a bit!
