Move the large astronaut on the wall above an exit at L'Enfant Plaza to the 7th&Maryland exit, the closest to the Air&Space museum.
Currently there is a large astronaut on the wall over an exit at L'Enfant Plaza. It is not currently over the closest exit to the Air&Space museum and thus causes a lot of tourists to take the wrong exit. I also suggest increasing signage for the Smithsonian museums in general. I'd support even floor decals during the spring / summer months.
