Rusting machinery

I was intrigued recently when I stumbled on a website for enthusiasts who collect photos of wrecked cars in the Pyrénees Orientales. They go to considerable lengths to track down those cars that have fallen off cliff roads and lie rusting and covered with undergrowth at the bottom of valleys. Some have been there for a long time and become classics worthy of restoration. Shipwrecks also have their followings I sense, therefore, a blip opportunity developing for rusting agricultural machinery that lies scattered around everywhere on the fen. There must be someone interested in that sort of thing...
