Thank you @andersun ! Great list idea. I also included my excuses for not going so far.
  1. National Museum of African American History and Culture ✅
    We finally got in! After months of trying to get tickets. There was an hour line to get into the history portion so we stuck to the culture floors and will have to go back!
  2. Arlington National Cemetery
    😳 how have I not been? I have driven by many, many times.
  3. DEA Museum
    Right next to Pentagon City Mall but the hours are weird. My husband has been.
  4. Phillips Collection
    Art! One of the things that joins a lot of the museums I haven't yet been to is that they cost money. There are so many free museums! But I should just suck it up and pay for some of them.
  5. Dumbarton Oaks
    See above
  6. ✅ National Cathedral
    We did the tower climb and saw the flower market.
  7. National Postal Museum
    This is a Smithsonian so it's free. I'm a Smithsonian completionist I guess.
  8. Corcoran
    Not free, see above.
  9. ✅ Air & Space, Udvar-Hazy Center
    Finally ventured out! It's so huge and impressive. Seeing Space Shuttle Discovery was awe inspiring.
  10. White House Tour
    I mean I live here so I dunno why planning way in advance is a problem. But maybe, um, not in the next four years...
  11. Washington Monument (going up in it)
    Closed until spring 2019 🙄
  12. Dupont Underground
    This is cool and new and just now available for tours!
  13. ✅ Kusama exhibit at the Hirschhorn
