The flag that inspired the national anthem was 30 by 42 feet, with 15 stars and 15 stripes. At Fort McHenry today, visitors still help raise a replica that exact size. Every morning at 10 a.m., weather permitting, rangers hand out the edges and whoever is on the lawn helps hoist it. The original flag hangs at the Smithsonian. The replica still goes up every morning, over the same fort walls.
