 All right, Jimmy, trying to stay cool out there. It is a federal holiday, of course, and that means schedule changes and closings. Metro Rail is open until midnight, but it's operating on a Sunday schedule today. After 5 o'clock today, all rail and bus trips on Metro are free. Parking is free all day at Metro lots.
