Smithsonian National Air & Space Museum is one of many free museums today

Museums all across the U.S. will be waiving their admission today for the sixth annual Smithsonian Magazine Museum Day.

Each household is allowed one "Museum Day Ticket", which entitles them to free admission for two guests into one participating museum. 

With over 1,300 museums opening their doors for free on Saturday, visitors will more than likely have no problem finding one nearby. 

Smithsonian.com has a full listing of all the museums for your visiting pleasure. Definitely a great (and affordable) way to spend a Saturday.
