During an intense lightning storm which led to a tornado warning, I saw something in my yard which no one has yet explained. There was ordinary lightning near the ground about 30 feet away. Then I saw the whole front yard filled with fine vertical lines, evenly spaced, maybe a foot or less between them. No sound or feeling of shock or tingling. I couldn't stop to look closer, having to evacuate self and animals. I wonder if it was related to the wireless fence around the property? After reading a lot about lightning, I began to think it was magnetism, which some birds can see due to a substance in the retina. Any serious comments would be welcome.
