In the twentieth century, red, white, and yellow have been the colors of choice of most farmers, often with the trim in a different color. Just another opion added to the red barn theory. I'm a teacher in Williamsburg and have been researching and photographing tens of hundreds of old barns in my native State of Virgina, especially in our Shenandoah Valley. Now, there are more of us out in the hinderlands in America. When I go out on sunny weekends, with Nikon, my role switches to Indiana Jones.

We are trying to find information on this style of archetcture. There are only 2 remaining like this around. Plan to apply for National Historic Register when we are done. It was built in 1901. I bought a 135 yr old house and when remodelling found barn board under layers of plaster.
