I went there for the showing of the "Un-American: Japanese Internment in Our Backyard" where a curator has gathered and displayed events when the Japanese American population of the U.S. were rounded up and interned during WWII. There were 16,665 JAs interned, and cranes were made and gathered from around the world, one for each internee. As it turned out, over 17,000 cranes were made and displayed. It was a very educational and moving photo event.
The museum itself is small, which I'd expect since it is the museum for one of the suburbs of Phoenix. The displays will be up and the museum open till around mid September of this year, at which time it closes for a year or so to have a bigger facility built on property. There are historical displays in the museum for the city of Chandler. I didn't really view those displays. I would be interested in seeing the new museum once it's built and open.
