In our normal daily life, the outdoors is almost irrelevant. It is simply a transition between indoors. Walking, especially in long excursions, reverses this. The indoors become the variable means that allow one to stay outdoors as much as possible. The outdoors, the landscape, become home.

In walks that extend over several days, during major expeditions, everything is inverted. ‘Outside’ is no longer a transition, but the element in which stability exists.
