What's the one place we can't miss in D.C.?

Question

We're heading to D.C. in September. Where's the one place we shouldn't miss? We're going out there for our 10 year anniversary. We're staying close to the National Mall and we are planning to go to the Zoo for sure. Any suggestions would be greatly appreciated.

Answer 1

Any of the Smithsonian Museums -- there are plenty to choose from, and they are all free to visit.  The Air & Space Museum is definitely amazing.

We went to the National Postal Museum.  It was remarkably interesting.  Who knew that the mail could be so interesting?  They had great displays, loads of interactive displays, and a whole section on crime -- some of the world's most notorious thieves have been arrested by committing mail fraud.  Super fascinating!  Who knew?

Washington & Lincoln Memorial, and the other war memorials nearby are all very interesting to see.  Lots of history.
