Chapters 11-15

Chapter 11 begins by telling us about how the relationship between farmers and their land is becoming less and less because the farmers don't actually live on the land. They no longer have a deep understanding of it. With everyone moving to California, there aren't many people left to take care of the land like it should be. Many of these farmers and there families struggle to make it from gas station to gas station and begin to worry that the land ahead of them is not really what it is said to be. Multiple people tell the travelling families that the country is not large enough to support everyone's need and to go back where they came from, yet the families move onward.
In Chapter 13, the Joads stop at a service station where a fat man harrasses them about not having money to pay for gas, and he says that everyone who stops there begs him to trade a gallon of gas for something that they have such as shoes, mattresses, dolls, etc. While they are getting water and resting at this service station, their dog is hit by a car and the only people that seem to show any emotion for it is Rose of Sharon and the kids. Rose worries that seeing a sight that is so horrifying will harm her baby, but Ma and Connie reassure her. The fat man agrees to bury the dog, and the family begins on there journey again.
As it gets dark, they stop on the side of the road next to the Wilsons. Grampa starts acting strange so the Wilsons let him rest in their tent. Before long, he passes away of a stroke. So they bury him there with a letter that says who he is and how he died, and Jim Casy says a few words in his honor.
