In some variations of the challenge, loosely based on military exercises, adults trail the teams of children, but refuse to guide them, although they may leave cryptic notes as clues. To make it more difficult, adult organizers may even blindfold the children on their way to the dropping, or drive in loop-de-loops to scramble their sense of direction.

Sometimes, they hide in the underbrush and make noises like a wild boar.

If this sounds a little crazy to you, it is because you are not Dutch.

The Dutch — it is fair to say — do childhood differently. Children are taught not to depend too much on adults; adults are taught to allow children to solve their own problems. Droppings distill these principles into extreme form, banking on the idea that even for children who are tired, hungry and disoriented, there is a compensatory thrill to being in charge.
