I love Detroit... well, the history of Detroit.
I go to Ann Arbor many times a year to visit friends, and once I asked my friend "take me to Detroit!" He asked, what the hell would I want to go there for? But he took me anyway. One of my hobbies is taking pictures of graffitti, and Detroit proved to be fertile ground. But my poor friend almost had a heart attack as I kept making him stop the car while I got out to take pictures in what were obviously some of the worst neighborhoods I'd ever been in (and I'm from Rochester NY!).
I had heard how bad it is there, my dad even told me not to go there, but I had to check out the home of the mighty MC5, The Stooges, home of the 2nd Industrial Revolution, the home of the Motown Records sounds, the factories of the great war machines of WWII...
It was horrible. Every 3rd building was burned, locked up, bombed out, destroyed, delapidated, or otherwise ruined. I'd never seen anything like it. Two rock&roll guys in an Oldsmobile, and we were the only white people I saw for miles.
That was an awesome website, thank you so much for linking it.
