I thought of that, believe me!
The good news is that we were at the JW next door to the White House (we saw Marine One land and let the President out -- well, we didn't see the President since they blocked the street off) and it is close to the major sights.
I took a private guided tour or two while we lived there (nine months.) But I hated the area. I hated the climate. I was very unhappy. And then my mother got sick, so I had a chance to leave.
I won’t go back; though the countryside was beautiful, and we toured a lot of the battlegrounds. it was just not “home” to me, which surprised me, because I was a military wife, and adjusted to my environments.
