Eternity

Want to preserve your love for eternity? Try this, secure a lock on a bridge and throw the keys in the river.

We have seen this tactic in Rome, Paris and as of today in Munich. As we learned though, your love will be kept safe in the case of Paris only for a year. The tourists-in-love are so many, that the police removes all locks once a year. I guess the couple in the picture has secured their lock somewhere else.
