If you’ve ever visited Washington DC, then you probably went to at least one of the world-famous Smithsonian museums. All of the Smithsonian museums are free to visit, and in that spirit, one day each year the Smithsonian Magazine hosts Museum Day, when many museums all over the country open their doors free of charge.
