In the past John and our children, as well as other extended family members, have visited this museum at least a couple of times. I seemed to be otherwise engaged (usually working) when they went. Before going there Sunday we had quite a discussion as to whether it would be an appropriate place for our grandson, who now is a walking dynamo. John said it was not a place for young children. Melissa checked it out on- line and the information she received there told her otherwise. It was a bit dicey getting downtown to 16th street because of a parade going on which blocked off many streets, as well as a graduation at Harris Stowe which added more traffic to the congested streets. We almost returned home, but did find a way to circumvent the bottle necks and get to the museum. My initial impression of the place was that there was fun to be had ahead of us. A bus hangs off the roof of the three story building, tunnels and stairs surround it.
