This is a cool photography site: Modern Ruins. They only take photos of modern technology that has been abandoned. There are also stories collected from people who experienced these ruins. I really love this one.

"So you've taken pictures of the Alcoa factory that was my childhood fascination? Did you sneak through a window, and look up at fallen dust blanketed stairs? Did you hear loud thumping in the dark? Those were the sounds of the criminals who lived in that factory and plotted their crimes through out the night. I was always very quiet in there, and always got out very fast. But even when I was outside, surrounded by faded, scragally grasses and bright yellow danger signs I could still feel the life that had once come to work every day. I could still smell the sweat and see the small paths left by heavy boots in the ground. But hey, I was only eight and I really did believe that each time I left that edifice, there was a man watching me leave from the top window. He was probably an ex-worker who lost his livelihood when he lost his job, and that was probably his oil soiled, stiffened, leather glove that I had just stepped on, so I began to run as fast as I could.... maybe that's why I spend my time in the places that time has passed by."
