NTS & B Second attempt on cable stayed bridge

Am trying a different type of nylon cord. Cord I first used was clear. I was trying to use LEDs to change the color on demand, but the cords would not show up. The cord on the side closest to the camera is light blue weed-eater string. Shows up a little better in they daylight, but no help with the LEDs. So much for that idea. I plan on restringing the other side with the blue cord when time permits.
