From the “Too Much Time on the Metro Department”…If you ride the up escalators in the Rosslyn station and want to save time, make sure you choose the middle up escalator (second from the right). Over the course of an entire ride, you’ll finish two steps faster than the right-most escalator. A whole two steps saving you three seconds! Amazing! Check it out and you’ll be amazed, or you’ll just roll your eyes that someone would notice this type of thing.
