“Bonneville Power Administration engineers yesterday completed laying the world’s longest submarine power cable, a line 7 ½ miles long linking Greens Point near Anacortes and the San Juan Islands in Puget Sound. Some 500 persons lined the shores, motor boats paused and even a ferry boat left its course so passengers could watch as engineers laid the final five miles of high-voltage cable along the bottom of Rosario Strait to Decatur Island.” –AP News
