On June 14, 1777, the Second Continental Congress adopted the official flag of the United States, but it wasn't until 1949 that congress passed an act establishing a National Flag Day. So as far as holidays goes, this one is pretty young. But that doesn't mean we're not celebrating the dickens out of it.
With the help of stock photography, we set out to illustrate how Americans are celebrating today's national holiday, and the results are both festive and surprising. Pick your favorite and let us know how you're marking the occasion.
