It's been a long time since I've been to Detroit, as in over 25 years, so I am sure my memories are skewed. and I think at the time is was thriving, not dying. Although I am hoping to make it up there in the next year or so to visit with an Uncle I haven't seen in far too long.
Recently I visited Cleveland and I must say it didn't do a whole lot for me. I was there very briefly though, so maybe that doesn't count.
I am surprised that Chicago is clustered in with these other cities, as it doesn't seem very rusty or depressed to me after my last visit.
I am glad we ended up in Pittsburgh. There is still decay... but there is also so much progress in it's efforts to renew, rejuvenate, and rejoice in what it does have to offer.
