Project: Years ago while on assignment for Southern Living Magazine, I was stuck at a train crossing in Folkston, Georgia. A seemingly endless line of rumbling lumbering boxcars rolled by. At first I only saw the dull browns, yellow and grays of the cars. Bright splashes of color started to appear. Graffiti painted on the cars broke the monotone of dullness. Painters across the country had added their touch to movable metal canvas. Now when I pass the occasional train siding, I keep watch for the work of artists I still don't know.
