At 12:49 on the DVD as Willie Grier is walking down the road in the moonlight, he seems to be walking on a path in the middle of the road. At 10:23 in the 3rd (director and cinematographer) commentary Aaron Schneider mentions that Bill Eaton, who owned the farm where location shots were made, assisted by spreading quarry gravel (granite dust at 08:44 in the documentary "Behind the Scenes") over the yellow lines to conceal them and avoid an anachronism.
