A full year of open doors at the National Museum of American History, combined with a robust bump from the crowds in Washington for the inauguration, brought a record number of visits to the Smithsonian in 2009. Last year, according to numbers released this week by the Smithsonian, the institution's 19 facilities received 30 million visits. The American History Museum had been closed for two years for renovation and the addition of a gallery for the Star-Spangled Banner.
