Went on free day. I was not at all impressed. Too many screaming kids and the museum itself is definitely geared towards children with nothing to impress adults. As a museum it was sort very disorganized and it seems some displays were missing. The signage was poor. The dinosaur displays were impressive along with some of the minerals, but they were just stuck there without much chronology. It was weird to have native american displays and the jail in a museum of "natural history". It's sort of a hodgepodge. The kids seemed to be having fun slamming the jail doors and screaming and running around. I expected a bit more even for a museum in Mesa and I also expected more from parents regarding their children. Won't ever go back.
