In the latest instance of White House vandalism, construction of a helipad at the White House has begun.
I'd post a photograph of it, but the only photo I can find is copyright protected, so I'll abstain. I will note, however, that the pad is way, way, too close the White House itself.
This is frankly a really bad idea, and some bad result will occur sooner or later. There's no excuse, however, for building a helipad that close to a structure, let alone an 18th Century structure.
