Locks of love

They're commonplace in Paris (on, say, the Pont de l'Archevêché and the Pont des Artes) and they show up even farther afield -- in Cologne, Florence, Uruguay, Taiwan. But I haven't before seen any "love locks" in New York.

Is this single lonely lock -- painted purple, pink, and white, and signed with the initials J and G -- affixed midway across Pulaski Bridge the start of a trend?
