Travels with Charley page 780

"But maps are not reality at all -- they can be tyrants. I know people who are so immersed in road maps that they never see the countryside they pass through, and others who, having traced a route, are held to it as though held by flanged wheels to trails"

Although John Steinbeck's definition of the road trip seems to slightly differ from Kerouac's, in this quote we see how the definitions are similar. Kerouac believes that a road trip must not be planned out and spontaneity, mystery and adventure are the most important characteristics of a road trip. However in Travels with Charley we get a slightly different definition from Steinbeck, that a road trip should be planned and laid out, as Jessica explained. In this quote however, we see that although there should be some planning or future destination in mind, along the way the road trip should still be spontaneous and adventurous. I think he is saying that people are so consumed with getting to their final destinations, following maps so closely, that they forget to look out their windows and see the beautiful parts of the country they don't normally get to see. They don't take full advantage of the road trip because they are so obsessed with staying on track with the map and miss out on the "adventure" part of the trip they are taking. It is important even when we have a final destination or a planned general route to follow, to not forget to look at our surroundings and soak up the beauty and the uniqueness of each different place.
