Highways
"According to the Federal Highway Administration, there are 3,871,000 miles of roadway in the country. If we take 50 feet as an average road width, including shoulders, this translates to an utterly staggering 36,657 square miles of land used for this purpose---more than the entire state of Indiana!"
