Last September I came across a site devoted to photography of the Hell that is Detroit, Ruins From Old Detroit. Here is another photographer, James Griffioen, who also has been wandering around the living museum of Detroit. Instead of focusing on decayed landmarks he looks for absence, the empty blocks, the caved in houses, the feral dogs. The archeology record of grand buildings, palaces, shrines is glamorous, but the analysis of humbler buildings is also very useful.
