Nearly 200 years ago, a tattered flag, its broad stripes and bright stars still gleaming through the smoke of a fierce battle, moved Francis Scott Key to scribble a few words on the back of an envelope -- the words that became our national anthem. Today, that Start Spangled Banner, along with the Declaration of Independence, the Constitution and the Bill of Rights, are on display just a short walk from here. They are America's treasures and we must also save them for the ages.
