I guess my question, when I look very closely at the Pentagon photographs you've provided is this. Why would anyone need to put an areal marker on the Pentagon. It is after all, a Pentagon....I'm guessing one of...well...one of it's kind in DC. It seems like even from the air it might be difficult to miss. Or I mean, if you were going to see the white line on the lawn, the proposed areal marker....you'd probably have already seen the great big pentagon itself.
