 It's 8.52. Today, of course, is a federal holiday, and that means scheduled changes and closings. Metro Rail is now open. It opened at 7, will stay open until midnight. It's operating on a Sunday schedule. All rail and bus trips will be free after 5 p.m., and parking at Metro lots is free all day today. Trash and recycling will be picked up as usual today in Arlington and Fairfax counties, but those pickups will be delayed a day in several parts of the region today.
