Here's a breakdown:
* Oklahoma: The Joad family originates from a small, impoverished farm in Oklahoma. The story begins with their struggles during the Dust Bowl, which forces them to migrate west.
* California: The Joads, along with thousands of other Okies, head to California seeking work and a better life. The novel explores the harsh realities they face in California, including poverty, discrimination, and exploitation.
The novel specifically mentions various locations, including:
* Sallisaw, Oklahoma: This is the Joad family's hometown.
* Route 66: The Joads travel along this famous highway on their journey west.
* California's Central Valley: The novel focuses on the agricultural areas of California, where the Joads find temporary work as migrant laborers.
* Weedpatch Camp: A migrant labor camp where the Joads find temporary respite from the harsh conditions.
So, while the story begins in Oklahoma, the heart of the novel's action and social commentary takes place in California, particularly in the Central Valley.
