Driving cross country in southern Lower Saxony one can't help but notice them: gigantic plastic tarps covering asparagus and strawberry fields, mountains of sugar beet and stacks of hay bales. They appear as silvery fleece, flapping in the breeze, forming snow-clad mountain ranges and mighty glaciers. They also pretend to be gigantic monsters from Middle Earth, lurking behind bends in the road and staring at the passer-by with monstrous rubber tire eyes. And they fascinate the photographer with their lines and textures and the vivid associations they evoke.
