How does Dore Schary use imagery in Sunrise at Campobello?

The imagery is related to the setting. The play opens at the sprawling summer home of Franklin Delano Roosevelt (FDR), located in the deep woods of Campobello, New Brunswick, Canada. It is August 10, 1921, before FDR was elected president of the United States. As dusk approaches, members of the Roosevelt family return from a day of outdoor activity. Eleanor discusses the day's events with her husband and children and arranges for dinner.
