Creeping Shadows Full of Light

This morning I went back to the old farm house at the end of the dirt road.  The shadow was creeping down the side of the side porch, so I marked off where it was, and painted real fast.  By the time I was done, the shadow was all the way down like a curtain to the floor.  But I managed to capture where it was when I arrived on the scene.  It helped to have done the preparatory watercolor a few days ago.  What I found interesting to deal with was that the shadows were full of light.
