37 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.

Generally considered the geographical center of the country, Kansas is a state rich in history, having served as home to diverse Native American tribes for thousands of years before European settlement. Once called "Bleeding Kansas" because of violent clashes between abolitionists and pro-slavery settlers, Kansas now carries the nickname the "Sunflower State," earned because of its massive production of sunflowers, corn, wheat, and sorghum. In addition to agriculture, the state is also known as an aviation hub. Sightseeing is easy, as wide-open spaces dominate the landscape of the western two-thirds of the state, which includes some of the only remaining native tallgrass prairie in the nation. Eastern Kansas contains rolling hills and most of the major cities, which draw tourism with their lively art, nightlife, and music scenes.

Known as the "Grand Canyon State," Arizona boasts dense forests, deep gorges, sprawling national parks, and modern ski resorts. Native American reservations take up about a quarter of the state, housing several tribes and offering visitors a chance to discover the varied cultures of the country's indigenous population. A patchwork of diverse tourist attractions, Arizona features exclusive golf courses and upscale shops, as well as cactus-covered canyons and stretches of desolate desert straight out of old Westerns, perfect for a vacation far from the city bustle. Though the state still clings to its Old West flavor, its busy college towns packed with young students from around the world exude a cosmopolitan atmosphere.

The country's largest state, Alaska is also its least densely populated. America's final frontier, the state lies on the Arctic Circle and features some of the highest mountains in the United States. Today, several million people flock annually to the state's pristine wilderness areas, which shelter a diverse plant and animal life and offer a great selection of things to do. Tailor-made for adventurous types wishing to leave civilization behind, Alaska can also be an extremely expensive vacation destination, with few transportation options and much of its land accessible only by plane or helicopter.
