The chapter that I thought was the most engaging was chapter 10. This is because this is the chapter where the Joads get very anxious and excited to leave for California. In fact, they get so excited that they decide to get everything packed up and ready to go that very night. It is also a pretty important chapter because it shows how Grandpa is attached to the land. When he gets up in the morning, he does not want to leave with the rest of the family. He wants to stay with his land. The theme of this chapter is definitely people being attached to their land.
