Motion

"But I had to get going and stop moaning, so I picked up my bag, said so long to the old hotelkeeper sitting by his spittoon, and went to eat. I ate apple pie and ice cream- it was getting better as I got deeper into Iowa, the pie bigger, the ice cream richer."--page 15

As Sal sets off, he is in constant motion. From point to point, always racing to his next destination, and he stops only when he cannot help but to. At this point the ultimate destination feels so close, yet just out of reach. There is a sense of urgency in the tone; the desire to get to Denver is palpable, and it seems one of the reasons Sal feels the need to get there so quickly is because he feels alone, as solitary travelers often do.
Even though he makes a friend in Eddie, the desire for familiarity is strong. In Denver, he will have Carlo Marx, Dean Moriarty, Chad King, Tim Gray and other friends. Until then, the comfort of apple pie and ice cream seem to be the only constant he has.

I wonder though, will Sal really be content when he does eventually reach his final destination? Is his goal really just to make enough money to support himself while he finnishes his book as he claims it is?
