They used a lot of these buildings as background for the show.
The problem with Detroit was it was far too dependent on the Auto industry. I remember going to a convention in Detroit in 1996. Non of the out of towners ventured out beyond the area.
Cleveland, a much smaller city than Detroit, had the good fortune of having some civic minded people who worked hard to revitalize several strategic hubs across the city.
It took a long time and a lot of people working together. A few, a very few, lost their way and did not develop beyond the cool bar and restaurant area.
The Cleveland Clinic and University Hospitals anchored their large Campus around Case Western Reserve which has a MD program.
The fantastic Theater District has finally blossomed after 35 years of people raising money, carefully developing. The development around the area pushed east and now Cleveland State and the Theater District flow into each other.
One thing I would like to point out. Detroit seems to have bet a lot of it's future in Legal Gambling. The development didn't seem to go outside the Casino's.
Cleveland waited and put the Casino between the Flats or River area that once blossomed and the Sports Arenas. The Redevelopment of the Flats Oxbo association is managing the area by making the area into a neighborhood.
There are some real Bleak Areas, the area where those recently captives were found. Still, the city has a real chance to blossom the further we get into the 21st Century.
By the way, we had our default decades ago before anyone was thinking of redeveloping. It was that moment that people decided to work together with realistic goals.
