Who has seen a Love Lock?

The SO and I were recently in Munich, and we noticed padlocks secured to a metal bridge in a public park. On the locks were initials, either carved or written in permanent marker. We then started to notice locks in other locations.

It turns out that they are Love Locks. Apparently, it’s a fad in several European countries. I’m curious if this has made it to your area. The article mentions that it’s happening in Toronto, Canada, so it’s made it across the Atlantic pond, but I haven’t noticed any here in the US.
