In the last couple of years, a trend has picked up steam: clipping padlocks to the Brooklyn Bridge. Usually the locks are inscribed by Sharpie, or even engraved, with couples' names, like the old heart-carved-in-a-tree. They've been accumulating so quickly that people have taken to locking locks to locks. Then every once in awhile, the maintenance guys come along with giant bolt cutters and get rid of them. So much for 4ever.
