I'm sure it's a great science center. It's hard to believe it's all free. Parking at the observatory and walking across the bridge avoids parking fees and is a pretty cool experience in and of itself. The reason for four stars is because it's so popular, it was overly crowded on a Sunday and therefore not as enjoyable. We left and went to the far less crowded Art Museum and found it much less crowded and therefore more enjoyable.
