Smithsonian magazine — the publication of the nation’s preeminent steward of history, culture, art and science— is offering free admission to hundreds of museums across the nation on Saturday, Sept. 26.

To get the deal, you must print a special Museum Day admission card at the Museum Day Web site. The card is good for free admission for two people. There is no charge to print the card, but you will need to fill out a short questionnaire.
