In Paris, there’s a bridge where people attach padlocks so their love remains strong forever or until the padlock, eaten away by rust, crumbles and falls into the Seine. Of course, most of them are young people from whom love flees when their youthful impatience takes them to new horizons/partners.
In NYC, they had the same idea. As everything is bigger in the US, it could not be any bridge, it has to be: the Brooklyn Bridge.
Same story: a bridge + cheesy lovers + a padlock.
