Chester Grimes, made in 1971 by Herb Di Gioia and his partner, the late David Hancock, has not been available for public viewing in years. It tells the story of a 70-year-old logger who still worked in northern Vermont at that advanced age with his team of horses. Di Gioia, who lives in Sutton, Vt. and is well known in the world of film documentary and ethnography, pioneered “observational cinema” by focusing on exploring the lives of ordinary people.
