Read this paragraph from the text.
"He was in Canada. Before the border and after the border looked just the same—it was an imaginary line, after all—but he felt different. He turned the radio off and drove in silence for close to 30 minutes. The windshield wipers had stopped swinging from one side to the other, counting time. They were stuck, solid, to the glass, shuddering lightly in their icy casing. Michael pulled onto the shoulder, jumped out of the car and tried to pull the wipers from the window with his gloved hands. They wouldn’t budge. Bits of hail stung his uncovered face. He took the scraper from his trunk and began to assault the front of the car."
