"We got pickin’ tomorra," Ma observed. "Mile north. Twenty acres."
– John Steinbeck
The Grapes of Wrath, Chapter 28. Ma Joad shares some good news with Mr. Wainwright, whose family shares the boxcar with the Joads. She has succeeded in getting cotton picking work for the Joads from a small farmer she had a conversation with. This reinforces Ma’s role as leader and preserver of the family. The quote is also about the theme of hope.
