This 19th century farm once had hundreds of acres under till. The early morning sun washes out the red, and is more easily seen in the shadows. At one time, farmers made their own paint for the barns, made up of milk, rusted bits of metal (there is never any shortage of scrap steel around a farm, as I've found from using a metal detector on my former vineyard), and lime. I've used real milk paint before, and will sour rapidly if not used at once. Not pleasant to smell!
