It's a nice site -- from the back of his stone, you can see the Washington Monument in Washington DC. Some of the other DC sights can also be seen from there.
I've attached a few photos of the stone that I didn't post, two of which are from the back of his stone , there is a tree a couple of rows ahead of his stone, so that looks nice in the spring/summer/fall when there are leaves. You can see the Washington Monument to the left of the stone, through a tree. Photo credit and description: A. Horan
