In Germany... Couples will take a lock, and attach it to the bridge's fence and throw the key into Rhine for love and good luck. So, all the way across the whole bridge the fence is covered in locks!
I always wanted to go to Venice and I'm glad I got to. Italy is a magical place that I was able to cross off my bucket list... Unfortunately Venice was a bit of a dissapointment for me, I personally felt as if I was walking in a sewer system, it was not as romantic or amazing as I had hoped, but was definitely worth going to.
