Steinbeck traveled across Wisconsin and Minnesota toward North Dakota. He traveled along U.S. Highway 10 through St. Paul on an "Evacuation Route" that would be used in the case of a nuclear attack by the Soviet Union. He called it "a road designed by fear" (p. 129) and it sparked one of Steinbeck's many realizations about American society: the fact that the country was driven by fear. Once through St. Paul, he went to Sauk Centre, the birthplace of writer Sinclair Lewis, but was disheartened to talk to locals at a restaurant who had no understanding of who Lewis was.
