A field next to the "Stone House" at the Manassas National Battlefield Park. I liked the fence leading the eye to the path up the hill to the tree silhoutted against the bright blue sky.
I had spent an hour or so shooting the stone house as a test of my 12-24 wide angle lens and the fence in this PAD scene can be seen at the right side of this stone house shot - http://www.pbase.com/image/46615554
