National Museum of American History

For what should be obvious reasons, this is one of my favorite museums on the National Mall.  Exhibits cover a variety of topics relating to our history ranging from televison and films, transportation, a collection of First Lady dresses worn on the event of the innauguration of their husbands, to winners of the Congresssional Medal of Honor, and so much more.
