On Saturday, museums all over the city will offer free admission to everyone in observance of Smithsonian Magazine Museum Day.
All you need to do to get in on the deal is register on the website to print out an admission card, good for you and a guest.
There are 18 museums around Philadelphia that are participating in the event, including the University of Pennsylvania Museum of Archaeology and Anthropology and the Rosenbach Museum and Library. To find all of them, all you need to do is type in your address.
Reviews of each museum from people who have actually visited them are available on the TripAdvisor, making it a little easier to decide where you would be most interested in spending your Saturday.
