Interesting idea. I do not know answer to that, but there might be a way to find those who do. Urban decay photography is enjoying a lot of popularity as of recently, mostly because of HDR technique. By googling it, you will find photographers who already did what you intend to do, in Detroit, Chicago, Gary, etc. and by contacting them directly I am sure they would be happy to offer advice (or even join you). I know one of them personally,
Brad Pogatetz, and
