Herbert decides to walk. He prepares himself for a long journey.		He has no choice but to walk along the highway. Overpasses writhe menacingly into the distance.
Herbert presses on, wind, mud, and flying debris whipping around him...		He can feel himself getting closer...
Shortly after Exit 20, Herbert comes across a stranded motorist changing a tire. He stops to check that he is heading in the right direction.
What should Herbert do?
Take the stranded motorist's advice, and go home and make a nice cup of tea...		Disregard the motorist, and continue on...
