If you walk the direction the Sun is shining you can see light shaded and dark shaded tracks. Just like striping a yard with a mower. I usually drag one foot a little to make sure the grass lays down. I pick out an object way out ahead and walk towards that object. The further away the object is the straiter your line. I always try to grid three different ways - north- south, east-west then diagonal.
