A wealthy beach town on the Central Coast of California still does not have cell phone coverage? I was amazed when a reporter from the LA Times called me today who is doing a story on Cambria, California's five-year battle to get cell phone towers built in their city of 6,500 residents to improve cellular coverage. She had a question that I could not answer but might by opening up the discussion to our users. What is the largest (most populated) city in the U.S. without cellular coverage?
