What kind of work did Rudolfo A. Anaya's grandfather do?

Rudolfo Anaya is an American author and teacher who is of Mexican descent.  His works tend to deal with the culture of the Southwestern United States and with Chicano culture in general.

Anaya was born in rural New Mexico in 1937.  He moved with his family to Albuquerque when he was 15 years old.

Much of Anaya's writing depicts traditional farming and ranching practices.  It is likely that he learned these from his grandfather because his grandfather (we are not told which of his grandfathers he is referring to in the essay) was a farmer.
