Quote #10

I found I was standing before acres of ploughed earth. There was a fence keeping me from stepping into the field, with two lines of barbed wire, and I could see how this fence and the cluster of three or four trees above me were the only things breaking the wind for miles. All along the fence, especially along the lower line of wire, all sorts of rubbish had caught and tangled. (23.49)
