Got there at opening expecting to walk around. They pretty much had to kick us out at five and we never even had lunch. took in Women who Rock and quite a bit of the rest, but never got through the whole second floor because there was just so much to see. Truly exceptional collection and just an outstanding facility. I especially enjoyed the giant mechanical orchestra they played for us and the very interesting artist gallery. Wish I did not live so far away, but I will do a "make up" visit asap. A bit pricey-tickets were $25 each with the "women" special exhibit-but well worth it.
