Sometimes having a working method of communication is pointless, because the person at the other end simply doesn't listen.
I've already pointed out that I often ride in areas WITHOUT A MOBILE PHONE SIGNAL. There have never been any phone boxes in these areas either. Did no one ride a bike before mobile phones were invented? If I have a mechanical I fix it. If I couldn't fix it I'd just have to walk.
Why and who would not listen, this post has been going around in my head since it was put there, I am having difficulty working out why this would be a reason not to carry a phone.
