Incoraggerei tutti gli americani a camminare molto spesso. È più che salutare: è divertente.

John F. Kennedy, 1962

Every once in a while you come across a farm or some dead little town where the liveliest thing is the flies. I remember one long, shimmering stretch where I could see a couple of miles down the highway and there was a brown dot beside the road. As I got closer I saw it was a man sitting on a box by his front yard, in some six-house town with a name like Spigot or Urinal, watching my approach with inordinate interest. He watched me zip past and in the rear-view mirror I could see him still watching me going on down the road until at last I disappeared into a heat haze. The whole thing must have taken about five minutes. I wouldn’t be surprised if even now he thinks of me from time to time.
