No, I didn't cut my hair...yet...but I'm open to suggestion!
While walking across a bridge near Notre Dame in Paris, I couldn't help but notice that there were thousands upon thousands of locks attached to the railings. I didn't know why they were there but I snapped a bunch of pictures to remind me to look into it once I got back to Barcelona.
It turns out that it's a tradition believed to have originated in China where couples etch their initials/names onto a lock, attach it to some local landmark (such as a bridge), and then throw away the key (into the water). I didn't see any locks while at the Great Wall but apparently there are a lot of them in the Badaling area where I was and that this was one of the original locks of love locations. The couples who attach locks at the wall hope that their love will last as long as the Great Wall has. Awwww.... :-)
I saw locks on at least three bridges that crossed the Seine near Notre Dame and the Louvre. The ones in these photos are on the Pont de l'Archeveche:
The trend is mostly in Europe (here's some in Cologne, Germany)and Asia right now but there are some places in the United States such as on the Brooklyn Bridge. There's even a town in Nevada that hopes to use locks of love to promote tourism! I'm not sure that I'd head out to the northern part of nowhere Nevada to attach a lock but I love the sentiment and its representation.
(Chicken and egg question: Which came first? The charity by the same name or the name given to attaching these locks? Hmm...)
