Lennie and George were run out of Weed. Lennie got into a lot of trouble with a girl because he wanted to pet her dress and she thought it was rape. They had to hide in an irrigation ditch from the cops who were trying to lynch Lennie.
They traveled very far from Weed. George and Lennie were on their way to their new job working on the ranch and on the way there George was telling Lennie about how one day they would have their own ranch with rabbits, chickens, pigs, and other animals.
