ourhurry to get from one place to another, we failed to see anything on the way. Air travel gives you a bird’s eye view of the world. When you travel by car or train a blurred image of the country- side constantly smears the windows. Car drivers, in particular, are forever obsessed with the urge to go on and on: they never want to stop.
