Today only, Smithsonian Magazine offers free general admission for two people to select museums when you fill out this short form as part of Museum Day. That's the best deal we've seen for this many museums since this was offered last year. Hundreds of museums across the U.S. are participating; New York State alone has over 100. Click here to find a participating museum near you. Limit one museum per email address.

If you noticed that The Smithsonian Museums in Washington, D.C., are missing, that's because they're already free.
