"She is the light of my life. She is more perfect the longer we are together. I am completely in love with her."
- Bono on his wife, Ali
The cover art for No Line on the Horizon is a photograph of Lake Constance, taken by Japanese photographer Hiroshi Sugimoto; titled Boden Sea, it is one of 200 pictures in his Seascapes collection. The image was the inspiration for Bono's lyrics on the track "No Line on the Horizon".
