National Academies HDR
Today I went to a Committee on National Statistics panel discussion on The Future of Social Science Data Collection at the National Academies Building (aka the Keck Center). I remembered seeing a photo on Flickr of this magnificent staircase capped on the top and bottom by mirrors. So I brought my camera. In 10 minutes of snapping photos I got a few sharable picks. This was my favorite.
