Nomads link together the places they pass by. They bring something form elsewhere and they take something with them. Deleuze said that nomads are nomads because they refuse to leave.
  The highway passing trough the landscape 
  without any links to its surrounding 
  is an expression of the monodirectionality nomads never cease to escape.
  The task of urbanists is to establish multidimensional 
  links between the environment, 
  social systems and people. For instance, the local 
  to the global, the economics to social 
  life, the urban to the rural.
