On The Road Ch. 4-10

"The greatest ride in my life was about to come up, a truck, with a flatboard at the back, with about six or seven boys sprawled out on it, and the drivers, two young blond farmers from Minnesota, were picking up every single soul they found on that road...." Pg 22

This part of the chapter is significant by the way it describes a traveler's spirit. Hitching a ride with 6 or 7 other strangers is totally random, spontaneous, and courageous. Moreover, friendship starts to develop. They drank, smoke, and speak of life. They bonded, like what a person would expect from a "road trip." At this point, I feel like the author is slowly becoming what Whitman describes as a "traveler;" being more carefree and more spontaneous.

Question: Why was there conflict between the members of his "gang" ?
