 On the National Mall, Grace Newton, WTOP News. Well, on this federal holiday, you know that a lot of places you show up to might not be open. One thing that is open and running is Metrorail, of course. If you want to take that to get down to the National Mall for the fireworks tonight, you can, of course. It's operating on a Sunday schedule, and you just do need to remember that Metrorail will be shutting down at midnight.
