I challenge you to find anybody, alive or dead, who can describe so completely and so eloquently the incurable desire to experience new and different places even half as well as John Steinbeck:
When the virus of restlessness begins to take possession of a wayward man, and the road away from Here seems broad and straight and sweet, the victim must first find in himself a good and sufficient reason for going. This to the practical bum is not difficult. He has a built-in garden of reasons to choose from. Next he must plan his trip in time and space, choose a direction and destination. And last he must implement the journey. How to go, what to take, how long to stay. This part of the process is invariable and immortal. I set it down only so that newcomers to bumdom, like teen-agers in new-hatched sin, will not think they invented it.
Once a journey is designed, equipped, and put in process, a new factor enters and takes over. A trip, a safari, an exploration, is an entity, different from all other journeys. It has personality, temperament, individuality, uniqueness. A journey is a person in itself; no two are alike. And all plans, safeguards, policing, and coercion are fruitless. We find after years of struggle that we do not take a trip; a trip takes us. Tour masters, schedules, reservations, brass-bound and inevitable, dash themselves to wreckage on the personality of the trip. Only when this is recognised can the blown-in-the-glass bum relax and go along with it. Only then do the frustrations fall away. In this a journey is like a marriage. The certain way to be wrong is to think you control it. I feel better now, having said this, although only those who have experienced it will understand it."
John Steinbeck, Travels with Charley (1962)
