English Lock Trees

So I got the opportunity to go to the "love bridge" yesterday with a few friends. Its a bridge next to a park in central Moscow. On the bridge are metal "trees" with loops in them for hanging "things." So what is traditional for newlyweds to do is to come to the bridge with a lock (a padlock, combination lock, etc.) with their names engraved on the lock. They then lock the lock to the tree to signify a long "locked" marriage. Its a cool tradition. I like it. If I get married in Moscow, Im going to do that! haha.
