When I was a youth, going cycle touring was a much easier affair than it is now. There was little in the way of choice for both cycling and camping. If you wanted to go away you took what you had and you went. If you got into trouble in a far flung place you had to dig yourself out again. That was all part of the joy and experience of travelling, even within the UK. Nobody worried about being away or being somewhere there was no phone signal because there was no signal anywhere. When you left home you were unattainable to the rest of the world unless you chose to make contact.
