Exchanging Pounds at Union Station

Since we still had about sixty dollars in pounds from our trip to England and France this month, we decided to take our Monday morning walk towards Union Station to exchange the money rather than stroll along the Mall. Union Station is only a few blocks away. If we take First Street and head North, we walk a straight path past the Library, the Capitol, and the Senate Office Buildings and get there in about twenty minutes. The Exchange is on the second level, where all the shops are located.  The first floor is still undergoing major renovation, and the place is teeming with travelers. The "basement" level has a movie theatre and fast food restaurants. A huge parking garage in the rear connects to the terminal. There is always a line of folks waiting for cabs, or getting tickets for the tour buses. My husband is dying to take a train somewhere. He absolutely loves Union Station and the city itself. Wen we started walking back home towards Pete's for breakfast, he always asks the same question..."how could you ever leave this place?" I'm not quite sure how to answer.
