Passage: We had gone into Washington D.C. for the day . It was me , my mother , my brother and my sister . We had lived in northern Virginia , just south of DC , for a number of years , but had never gone into the city itself . We did n't even drive through , or near it , unless we had to . The traffic was simply too horrible . This day though , we had a plan , we drove our car to a stop-and-park place and from there we caught a subway train into the city . Took a tour of the White House , saw , but did n't climb the Washington Monument , went to the Lincoln and Jefferson Memorials , then we headed into the big red castle , The Smithsonian . It was n't the first museum I had ever visited but it 's the first one that really made an impression on me . I remember the art , the dinosaurs , the airplane and rocket ships at the air and space museum . I always intended to go back but have n't made it yet . Question: They walked all over where? Option1: Washington D.C. Option2: Virginia
Washington D.C.
