Goof: Mulder tells Scully to meet him at "The Smithsonian". She can't do this, because The Smithsonian Institute is actually a series of buildings - 19 museums, 9 research centers, and the National Zoo, to be exact - not just one museum or building. She could not know where because Mulder did not specify one museum or building, and they aren't all in the same place; there are several on the Mall, but not all of them are there. The screen also says that they are at "The Smithsonian".
