The 13,000 sq mile U.S. Radio Quiet Zone is an area in West Virginia where all wireless transmissions are banned because of the large number of radio telescopes located there. (This official page shows a map of the Zone; an old Wired article is fascinating reading.) These high-tech telescopes have attracted unlikely neighbors, people who claim to have Wi-Fi allergies. In recent years, scores of people have moved to the area to escape the "damage" that electromagnetic fields can cause them. From the article: "Diane Schou is unable to hold back the tears as she describes how she once lived in a shielded cage to protect her from the electromagnetic radiation caused by waves from wireless communication. 'It's a horrible thing to have to be a prisoner,' she says. 'You become a technological leper because you can't be around people. It's not that you would be contagious to them — it's what they're carrying that is harmful to you.'"
