Quite impressive, the Green Bank Telescope (GBT) is located in Green Bank, WV near Cass, WV where we stayed. The radio telescope is part of the National Radio Astronomy Observatory (NRAO) facility. This particular telescope is the world's largest fully steerable radio telescope. The collecting area is 100 by 110 meters. For more see it's Wikipedia entry. The facility is located inside the United States National Radio Quiet Zone, no cell phone reception for you!
