Yes, but not until about 4 weeks ago. We picked up my wife's new car at a dealer in Rhode Island and drove it home to Atlanta. We spent the night in DC because it had some sites we both wanted to see and was near the halfway point.
Seems like a cool place and it was nice to see the monuments in the flesh. My father and many of his friends are Vietnam vets and I must say seeing the wall hit me a lot harder than I expected it to.
