Maybe we missed something, but it didn't seem as large of a museum as I might have thought based off of the $20 admission price... I think some of the exhibits were closed when we went too, perhaps.
The dinosaur exhibits were pretty cool, and something you wouldn't find in most other museums. The other ancient animal exhibits were pretty cool too.
The "hands on" galleries were very kid oriented, not much for adults.
$20 might be a little steep for admission.... I think we may have done the reduced later in the day thing though?
