I came across this video about the origins of the U.S. national anthem and its connection to the U.S. Flag. It's something I learned more about from my elders (who were part of "The Greatest Generation") than from teachers in U.S. history, and always found the story very moving. And gave me a different perspective on the fireworks on July 4th.
