Urbex (Urban Exploration) is basically gaining entry to old disused buildings and taking photos. There's a lot more to it than that, those who do it will travel thousands of miles looking for new previously unseen sites of dereliction. The top picture of the gas masks was taken at Chernobyl*, being a totally deserted town it is a mecca for Urbexers whose code of honour is to take nothing but pictures and leave nothing but footprints.
I had never heard of it until Ellis showed me a book last weekend. I don't propose to post a load of links, have a Google over the holidays or if you have no interest at all just wish you knew where that scrapyard was.
*A search for images of Chernobyl is not a good idea if you want a good nights sleep
