Saturday, September 28th is National Museum Day. You and a guest can get free admission to many museums throughout the United States. You will need to register and print a ticket. Remember, it’s two people per ticket. It does say one per household or email address, so I’m not sure if that will be enforced at each museum or not. I guess you can call and see if you and your spouse could each use one and get two kids in. It doesn’t hurt to ask! Here’s a link to the list of participating Arizona locations.
