Have you heard of the love locks of Paris? This is how it works...the happy couple puts their initials on a padlock, clips it onto one of two bridges in Paris and throws the key into the Seine as a symbol of their undying love. This is the Pont des Arts, a nice little pedestrian bridge that connects the 6th arrondisement to the Palais du Louvre in the 1st. Supposedly, this is the bridge to which you affix your love lock if you are in a committed relationship. The other lock-festooned bridge is over by Notre Dame and is apparently designated for those lovers who may not be quite ready for the commitment bridge. I hear that that "lovers fling" bridge has many more locks on it than this one so we'll have to check it out.
This lovely old lock caught my eye because the initials are those of my brother and father, neither of whom, I hope, traveled to Paris in 2009 with a certain LGB.
