 Susan says they won't stick around for the display, but for good reason. My daughter is going away to Fort Carson. She's an Army ROTC cadet studying to be an Army nurse, so she leaves tomorrow at 6 o'clock in the morning. So today we can't do it. On the National Mall, Grace Newton, WTOP News. Okay, the fireworks are supposed to begin just a little bit after 9 o'clock. Should last for about 17 and a half minutes there at the National Mall. Excuse me, that's not long enough. It doesn't feel long enough.
