Life belt: I think the sign is intended to stop photos of the security checkpoint for the Statue of Liberty ferry. The sign placement, though, is in the general park area and swarming with tourists and cameras. (I'll point out that so many of those tourists use flash for their photos of the Statue. Canikons apparently have great flash systems able to reach a mile distant.)
