The United States is less one destination than a dozen countries under one flag: Pacific coast redwoods and road trips, New York's density and energy, New Orleans' jazz and Creole cooking, Rocky Mountain wilderness, and desert canyons out west. Distances are real, Los Angeles to New York is a continent, not a hop, so most trips pick a region rather than trying to see it all. It rewards travellers who plan around a specific slice, a national park loop, a coastal drive, a city break, rather than one national itinerary.
