North View: The White House. Here's the White House through my zoom lens. That top floor on the roof is hidden from the ground by the white railing. That's probably where the Secret Service lurks. Lafayette Park is behind the White House.

There was a lawyer last year who was driving past Lafayette Park when a police car pulled him over. The officer looked at his ID. The lawyer asked him what he was pulled over for. Was he speeding? "No, sir," said the cop. "You're radioactive." The lawyer had just had a cardiac stress test where he swallowed a radioactive substance which was detected by sensors as he passed the White House, wary of a dirty bomb, ie radioactive material wrapped around a conventional bomb.
