Bostonist hadn't made any solid Saturday plans for this weekend until we read a post about "Museum Day" being held nationwide this Saturday, September 30. In honor of the Smithsonian, who has free admission to their great museums year round, other museums are joining in this free education ideology and will not be charging admission for this one specific day. In order to enter one of the participating museums for free, you must download and print out a "Museum Day" pass found here. (They say you can only use one that day, but we're assuming if you're feeling ambitious, you could print out three and hit up three museums on Saturday.)

While some of the participating museums are free all the time, there are some that you'll definitely save on: Norman Rockwell Museum, Stockbridge ($12.50); Louisa May Alcott's Orchard House, Concord ($8.00); Museum of Fine Arts, Boston ($15.00); Plimoth Plantation, Plymouth ($21.00). (Since when did it get so expensive to see period actors dress up as Pilgrims and Native Americans?) The Smithsonian website has the complete list of museums nationwide.
