The museum was a huge disappointment. It is not clear, first of all, where the museum is. Upon viewing the website, mocha.org, it appears as if this is a bigger museum than it actually is. There was one tiny gallery with perhaps five or six works displayed. Apparently they were in the middle of a down time, but we couldn't seem to figure out where they would have room for more works.
The museum is always free, although there is a charge ($5) for the hands-on aspect of the program. It is open Tuesday to Friday 10am to 5pm and Saturday to Sunday 12 to 5pm.
