One aspect of their country that Americans frequently overlook — and which is blindingly obvious to most foreigners — is that they live in a continent-size land of incredible variety. The United States contains within its borders the deep woods of Maine and the Everglades of Florida, the snowy peaks of Colorado and the sun-scorched deserts of Arizona. When Chicago is buried under snow, the rosé is on ice, poolside, in Los Angeles. And as well as booming, hypermodern urban areas, the country has cities like Boston that are close to 400 years old.
