19 days in United States Itinerary

More than the country of car-packed streets seen in TV shows and movies, the United States of America is a complex and diverse home to over 300 million people living in a wide range of landscapes and climates. From its big-city skyscrapers to its sprawling natural parks, the country's ''melting pot'' combines many ethnic groups that share a strong sense of national identity despite their cultural differences. A country of road trips and big blue skies, the United States harbors orderly cities filled with restaurants, parks, museums, and innumerable sightseeing opportunities, as well as pristine natural areas perfect for a holiday in the great outdoors. To see as much as you can of this diverse land quickly, drive over some of the more than 6 million km (4 million mi) of highways leading through deserts, mountain peaks, fertile fields, and giant urban centers.

Boasting a rich Native American heritage and named after the Choctaw word for "Red People," Oklahoma remains home to about 40 native tribes who speak 25 distinct languages. Though the state remains one of the country's top producers of agricultural products, most of its inhabitants live within two metropolitan areas, Oklahoma City and Tulsa. The state is home to the 500-million-year-old Wichita Mountains, noted for being the site of the oldest national wildlife refuge in the United States. Explore the state's pristine natural areas while on vacation here, but be sure to leave plenty of time to tour its characteristic small towns, known for their food, music, and cultural festivals.

Still relatively unspoiled by mass tourism, Mississippi epitomizes rich history and offers warm hospitality to those who vacation here. The Mississippi River forms most of its western border, so it's no surprise that this mighty waterway shapes the lives of people calling the "Magnolia State" their home. The river influences everything from the food they eat to the music they listen to. Perhaps the easiest way to discover Mississippi is to take a drive on the 715 km (444 mi) long national parkway, which follows a route used since pre-colonial times that's famous for its scenic beauty and attractions of historical interest. At the end of the parkway sits a town packed with nearly 600 antebellum homes.
