Protip: This is a really bad question to ask when visiting the National Mall. We have 8 buildings surrounding the Mall, and a total of 19 museums, 9 research centers and the National Zoo. A S.H.I.E.L.D agent should know better!
(We think she means the Smithsonian’s National Museum of Natural History in this case.)
I love that this is on the Smithsonian’s tumblr
Whoever does social media for the Smithsonian is awesome.
