"In the beginning of this record I tried to explore the nature of journeys, how they are things in themselves, each one an individual and no two alike. I speculated with a kind of wonder on the strength of the individuality of journeys and stopped on the postulate that people don't take trips - trips take people. That discussion, however, did not go into the lifespan of journeys. This seems to be variable and unpredictable. Who has not known a journey to be over and dead before the traveler returns? The reverse is also true: many a trip continues long after movement in time and space have ceased."
