the male had to be free to run interference for the woman, as ball-carrier, as it were. But that phase belonged to the prewheel stage of transport, when there was only the tractless waste of man the hunter and food-gatherer. Today, when the greatest volume of transport consists in the moving of information, the wheel and the road are undergoing recession and obsolescence; but in the first instance, given the pressure for, and from, wheels, there had to be roads to accommodate them. Settlements had created the impulse for exchange and for the increasing movement of raw material and produce from countryside to processing centers, where there was division of labor and specialist craft skills. Improvement of wheel and road more and more brought the town to the country in a reciprocal spongelike action of give-and-take. It is a process we have seen in this century with the motorcar. Great improvements in roads brought the city more and more to the country. The road became a substitute for the country by the time people began to talk about "taking a spin in the country." With super-highways the road became a wall between man and the country. Then came the stage of the highway as city, a city stretching continuously across the continent, dissolving all earlier cities into the sprawling aggregates that desolate their populations today. With air transport comes a further disruption of the old town-country complex that had occurred with wheel and road. With the plane the cities began to have the same slender relation to human needs that museums do. They became corridors of showcases echoing the departing forms of industrial assembly lines. The road is, then, used less and less for travel, and more and more for recreation. The traveler now turns to the airways, and thereby ceases to experience the act of traveling. As people used to say that an ocean liner might as well be a hotel in a big city, the jet traveler, whether he is over Tokyo or New York, might just as well be in a cocktail lounge so far as travel experience is concerned. He will begin to travel only after he lands.
