someone sweeping a section of paved ground that is covered in fine gray gravel or sand. There are small rocks and debris mixed in with the sand. The person uses a straw broom, and the sweeping motion creates swirling patterns in the material. The edge of the pavement is visible, contrasting slightly in color. At one point, the shadow of the person holding the camera falls on the ground. A drain cover is located near one edge of the paved area.
