The Warwick Valley has many old barns that are no longer in use. These artifacts reflect a lost age in rural farming in New York. Just a few decades ago every town in Upstate New York had several working dairy farms that served the locals and sold milk, butter and often cheese to the larger cities in New York and points south. I would say based on the size / age of the trees that this silo has not be used in over twenty years. If you look closely at the lower left of the image you will see an old chain-link fence, evidence that someone at some point cared enough to try to keep people away from their retired silo, but even that has passed with time.
I took this shot with my Canon GX1, which I have started carrying a lot instead of my 5DII, and I’m amazed at the quality image that it produces.
