Gee, James, out here in the modern world (where we have things like microwaves and electricity

), I don't know of anyone, who has a cell phone, that still has a land line. Plus there are several satellite options for broadband now.
Land lines used to work even if the power to your house was out because they had their own power, now I can't help but wonder what chaos will happen if everyone's cell phone goes dead due to a solar flare or cyber-terrorist attack!
