In many parts of the United States distances are so great that automobiles are necessities, not luxuries. Most American farmers do not live in villages but are sometimes kilometers from their nearest neighbor and even hundreds of kilometers from a town. Large-scale farming is common in the United States everywhere, but it did not become profitable until there were trucks and tractors. Trucks carry the farmers’ grain to storage elevators, milk to creameries and vegetable to market. Trucks and cars go wherever there is a road and the more than 6 million kilometers of roads in the country bring every farm into the circle of civilization.
