I have only ever hitch-hiked once. I was 16, at college, and had been potholing with a group of friends. Three of us, two girls and a boy, went off to catch the bus home and to be honest, we were so wet and muddy, in spite of having worn overalls, that I am not, on reflection surprised when the bus driver refused to let us on the bus. So we set out to walk - sixteen miles. It was late afternoon. We walked about five and decided to hitch. A car, driven by a man in a morning suit, stopped and asked us if we would like a lift! He put a rug on the back seat, chucked our mucky rucksacks in the boot and took us almost all the way home. I've never been so grateful to anyone. When I told my parents about it, my father was furious and made me promise never to do anything so stupid again! (It didn't seem to worry him that potholing wasn't just as stupid and potentially dangerous!).
