I think you are missing the point. "Ain't gwinna be no phone" to ride your CD on. Cut off ATT and VZ and you have basically shut down 90% of the net. The other would be hopelessly slow and overloaded. If we get to this level, short wave will be about it along with CB for short hauls. You would be basically giving away you position for a 500 pounder to come through your living room window.
If Obummer finds it prudent to shut down communications, we are already in deep pooh. All the talk about militia's and such will be pretty much total chaos. 200 million guns would be trained on their neighbors coming after your beans. The only real question is, would the police and military back the Constitution, or the Prez? Oath Keepers anyone?
