My take on Abandoned was mostly about buildings that have been left to fall down and vehicles abandoned to rust away, sometimes inside sheds that are falling down. You often see these places in the country. I also included one formerly abandoned city building that we photographed when we went to Sydney a few years ago.
The last one is interesting as it was one of several ruins I photographed when David and I visited the Flinders Ranges in South Australia way back in the late eighties when we first got a car. Many small farms were started there and later abandoned because in drought years farming was unsustainable. There were narrow gauge railway lines to these communities and they were also closed and the buildings abandoned. This photo is from a scan of my original colour print and played with in Picasa to get the sepia effect.
