I'd heard about the slow decline of Detroit, once the manufacturing hub of America. Automobile hub at least. But times have changed and changed for the worse, the city is in poor shape. You can read a short article on it here Michigan; Decline in Detroit. I spotted these photos today by Yves Marchand and Romaine Meffre on this slideshow. You can also buy their book here if so inclined. I might chase it up when I get back home.
