But the silence gives you a signal. Somewhere around the Virginia-West Virginia state line, the periodic buzzes and pings of our smartphones stopped.
Almost every radio station disappeared, too, except for Allegheny Mountain Radio, which broadcasts at a low enough frequency to avoid being banned.
The county still hasn't progressed to constant connectivity. That's because it sits within a zone designed to protect a sophisticated radio telescope at the National Radio Astronomy Observatory from interference. The Robert C. Byrd Green Bank Telescope is the world's largest fully steerable radio telescope.
