It appears the Floating Island has charted a new course -- away from any potential international intrigue.
From the website of public art organizer Minetta Brook: "With the UN in session, the Floating Island will not be visible from points north of 23rd Street on the East River until September 23rd when it will return to its normal route." What: Is this uninhabited island a threat to international security or something? Are they afraid that some pirates are going to board the barge and launch an attack on the world body's HQ?
For an "island," this thing sure is proving hard to nail down.
