The annual Smithsonian Folklife Festival, which will be held on the lawn of the National Museum the American Indian in 2015, is one of the best ways to get a close-up look at different cultural heritages from around the world. Like all of the surrounding Smithsonian museums, it is open to the public and completely free. - See more at: http://washington.org/article/summer-festivals-dc#sthash.GN1PWnLZ.dpuf
