What does George and Lennie want to buy?

George and Lennie dreamed of buying and owning a small amount of land, just like any man does. ( the American dream) They were going to work at the ranch just until they got enough money to buy the little shack, were they would grow rabbits, puppies, chickens, alfalfa for the rabbits, etc....

But the dream does not turn into reality, because of the sin that Lennie had committed. (killed Curly's wife)

And just like what crooks says about life...in chapter 3.

"Everyone wants just a little bit of land...."
