(The question occurs to one: Do youimagine there are sightseers who see sights just as they are supposed to? a family wholive in Te rre H aute, who decide to take the canyo n tour, who go there, see it, enjo y itimmense ly, and go home co ntent? a family who are entirely innocent of all thebarriers, zones, losses of sovereignty I have been talking about? W ouldn’t most peoplebe sorry if Battleship Point fell into the canyon, carrying all one’s fellow passeng ers totheir death, leaving one alone on the South Rim? I cannot answer this. Perhaps thereare such people. Certainly a great many American families would swear they had nosuch problems, that they cam e, saw, and went away happy. Yet it is just these familieswho would be happiest if they had gotten the Inside Track and bee n among thesurviving remnant.)
What I think Percy is getting at in this section is that people do not know how content they could be if they don't take the less beaten path. If they stick to the tours, and lookouts, they may be blindly limiting their experiences.
