How has tourism and travel changed from the beginning of America to today?

Tourism and travel in America have evolved significantly from the early days of the nation, when travel was primarily limited to local journeys by foot or horseback. With the advent of the railroad in the 19th century, travel became more accessible, allowing for cross-country excursions and the growth of national parks and resorts. In the 20th century, the rise of automobiles and commercial airlines revolutionized travel, making it faster and more convenient. Today, travel is characterized by global connectivity, technology-driven planning and booking, and an emphasis on experiential and sustainable tourism.
