Slate has some great photos of "Kerouac Road." To get you in the mood, here's a quote from On the Road:
[Dean Moriarty is rumored to have abandoned his family to join Sal in Denver for a trip to Mexico.]
"Everything was up, the jig and all. Behind him charred ruins smoked. He rushed westward over the groaning and awful continent again, and soon he would arrive. We made hasty preparations for Dean. News was that he was going to drive me to Mexico... We didn’t know what to expect. 'Where will he sleep? What’s he going to eat? Are there any girls for him?' It was like the imminent arrival of Gargantua; preparations had to be made to widen the gutters of Denver and foreshorten certain laws to fit his suffering bulk and bursting ecstasies."
