This is a MUST-SEE. We spent most of one day here and covered about 1/117th of it. It's just awesome (in the true sense of the word)! The exhibits are detailed for those who like lots of facts and very visual and interesting for those who want to get the gist. Something, literally, for everyone and anyone. Dinosaurs, history, animals, gems, Asia, birds, nature photography contest winners - seriously: WOW. The staff are knowledgeable and interesting, always engaging but not in-your-face. Very helpful. We ate lunch at the cafeteria, which is very nice also.
