A hidden gem in the desert. Lots of interactive exhibits and a neat bird show. Very pleasant staff.
We went for free as part of Bank of America's Museums on Us program http://museums.bankofamerica.com/
We got there when it opened and buzzed through within 2-1/2 hours because we were in a hurry to get to a show.
Lots to see, so we will try to stop back in the future.
