900 feet, not a great distance, the length of a football field. If I stood at my front door and drew a circle with a radius of 100 yards, the area within that circle would contain a small microcosm of a world completely familiar to me. I could walk much of it with my eyes closed and rarely stumble. Along with the familiarity comes a jaded eye... seeing these accustomed objects, landmarks & surroundings on a daily basis without really seeing... without really looking. Time for a second look.
