"Every kid got a turtle some time or other. Nobody can’t keep a turtle though. They work at it and work at it, and at last one day they get out and away they go – off somewheres. It’s like me."
– John Steinbeck
The Grapes of Wrath, Chapter 4. Jim Casy, the wandering preacher searching for the spiritual way, compares himself to the land turtle Tom Joad has for his kid brother. Like the turtle, he is a wanderer who goes from place to place and never stays in one location very long.
