The days when caravans could freely cross mountain passes and national borders are long gone. While it is constantly said that the world is getting smaller and there are fewer and fewer boundaries, never before have borders been more rigid than they are now. There can be no doubt that the map takes precedence over the terrain: the abstract red lines of the map are fiercely guarded on the ground by cameras, motion sensors, armed guards, and often also by physical barriers such as barbed wire, fences and walls.
