Yeah, I watched some documentaries about the decay of the automotive industry in the US and Detroit just has a huge area and not enough people to fill it anymore so there's bound to be tons of abandoned shit
It's not all that bad. I don't live there, but I've visited plenty of times. A lot of rust belt cities in the US (Detroit, Pittsburgh, Cleveland, Cincinnati, east/east-midwestern steel towns) are attracting millennials and new companies in droves because of their dirt-cheap cost of living and real estate. As a lifelong denizen of the rust belt, I kind of love it here, even though I felt a strong urge to leave up until I got a job in the opposite corner of the state from which I grew up. I also feel a fierce pride in the region, despite having little to defend. I know a lot of other people from the area feel the same way.
It's really cute seeing my friends from other parts of the country (especially, like, California) settle down in the rust belt and absolutely love it and never want to leave. My friends were recently charmed by an arcade in Pittsburgh called "Games 'n 'at" which, at 5 PM, dismissed all children and started carding everyone.
