Yeah, no kidding -- at least half of any reason to actually go there is gone. Now it's just another piece of grass that gets used occasionally for soccer despite being dangerously lumpy.
I'm glad that I got pics of it while it was still there. I have yet to go to National Harbor to see its new home, but I have a feeling that I won't like it; the pics I've seen make it look like a small afterthought between some huge buildings.
