Is there a museum in your local area that you've been dying to check out? This Saturday might be the day to do it. If that museum is participating in this weekend's Museum Day event, you can score free tickets for two people in your family.

Museum Day is an event sponsored by Smithsonian magazine in which participating museums across the country will open their doors for free to anyone with an event ticket. From Iowa's Herbert Hoover Presidential Museum to the Intrepid Sea, Air & Space Museum in Manhattan, you can find a museum to fit your family's interests.

To find a full list of participating museums, check out the Museum Day website for options in your area. You'll need to download a ticket, which is good for one person plus one guest. And keep in mind that extra stuff such as parking, special exhibits and events (including IMAX movies), won't be included with your ticket. But you will be able to use your ticket to explore your favorite museum or to discover a new favorite — and all for free.
