well...there's a lot of us in the utah/colorado area who camp on Nat'l Forest land out of our vehicles and campers, living in remote areas (harder and harder to find where there's no cell towers), coming into town only every week or more to get supplies. I myself lived in caves and in the desert with a backpack for years. It was rough and I often was malnourished, and most of my friends thought I was crazy. Even out there I was not safe from cell tower radiation. Finally I was able to buy property (through some very good luck), and now most people don't seem to think I'm crazy anymore, many of my friends are even starting to feel it themselves. Good luck finding a safe place, basically look for a remote valley or a canyon where the cell signals don't reach and where the population is scarce enough that they might not put in a tower.
