My son and I were walking along in a field and noticed a rectangular shaped object to the SE of us at approximately 350 yds from us. It hovered for about 2 minutes before descending below the treeline. It made no sound and we walked to the area near it and noticed a herd of cattle that appeared spooked by it. Approximate Latitude 35 degrees 55' 22.60 longitude 85 degrees 10' 52.65 at about 100 ft from the ground before descending below the treeline. Weather was clear with no clouds high 60s and no other objects in the sky.
