I ran across this rack at a park in Budapest. The idea is, when you fall in love, you buy a padlock, write your name and the name of your beloved on it and attach it to the rack. Then you walk down to the Danube and throw the key in the river. This is supposed to ensure that your love will last forever. It is quite a display, with hundreds of locks of all shapes, colors and sizes. There are even combination locks, for those who wanted to keep their options open. I like to think of this as the inverse of that hippy-dippy saying, “If you love something, set it free; if it comes back, it’s yours; if it doesn’t, it never was”. Here, if you love something, you need to lock it down tight!
