This Bear was surprised that there are no definitive threads about Detroit (unless my searches missed one). As planners (most of the urban variety) the Motor City is the ultimate textbook case of what can go right and what can go wrong in a large urban place.
To get the thread going, I have attached the first of a year-long series of articles from Time magazine. A good read. I would be interested in hearing the opinions of those who know the city well, regarding this first zine installment.
