You don't have to be a kid to appreciate the newly expanded and renovated Houston Children's Museum. We spent several hours there recently with our young visitors. It was a blast, and I would have been totally agog if I were a child. The water play area was especially entrancing for all of us - several stations to manipulate water, including a giant contraption with mechanized buckets, a spillway, and lock-and-dam system. 'Kidopolis' was also fantastic - an entire area of the museum designed as a little town with stores, a bank, a grocery, police station, ambulance, restaurant, and vet clinic with toys and play money where kids could live out their play fantasies. It even had a photo booth to pose for silly shots. The kids hated to leave, and I could definitely understand why. Being there brought me back to the magical world of make-believe and pretend - I still have my collection of plastic horses and gear saved out in the garage from that own period of my life. Do you have a favorite childhood memory or activity?
