I know you like this kind of subject too. I'm always looking for broken down and abandoned places. I'll be heading back to Florida in a month or two and the hunting there is not as productive as Cleveland. Give me a broken window, and I'm a happy guy!
I believe HDR is a huge contribution to the photography community. It's a great tool that can take a photo to a higher level of sophistication. And, as many others have said, it's fun.
