Here is a trivia question you may have trouble with: What is the name of the first “national river” in the United States? Is it the mighty Mississippi, the powerful Colorado or the historic Hudson in New York State? The answer, which may surprise you, is “None of the above.”

The country’s first “national river,” named as such in 1972, is the Buffalo River, which flows through the beautiful Ozark National Scenic Riverways, which itself was named a national park in 1964.

Now, do you know in which state you will find the Ozark National Scenic Riverways? Well, the answer to that question depends on whom you ask—a resident of Arkansas or Missouri.

The fact is that the Riverways and the Ozarks spread like a lush green belt across the nation's middle, spilling over southern Missouri and northern Arkansas, and residents of both states claim them as their own—and who wouldn’t, for all their bounty of natural scenic wonders and year-round attractions.

Located in the very heartland of the country, the Ozark National Scenic Riverways and the whole of the Ozarks region are ideal destinations for a memorable driving tour vacation in your 2010 Lexus ES.

For some of the country’s best canoeing and fishing or just a relaxing, carefree float, there is no beating the Ozarks’ crystal clear spring-fed rivers and lakes. Visit the Ozark Heritage Wine Region where the wineries have been earning worldwide acclaim for 150 years.

There are museums, historic mills and for American history buffs, some of the nation’s most famous Civil War sites.

The region’s state parks offer something for everyone – trout fishing in pristine streams, hiking through rolling meadows, even spelunking in some of the nation’s most spectacular and easily accessed caves.

Fall is an ideal time to visit the Ozarks, to enjoy such seasonal celebrations as the Arcadia Mountain Music Festival or any of the Missouri Ozarks fall festivals and county fairs.

Just as some say the Ozarks are in Arkansas and some say Missouri, some say the 2010 Lexus ES is a performance automobile while others say it is an outstanding luxury car. The fact is that it is both.

From its adaptive front lighting that allows both of the energy-efficient HID headlamps to turn to follow the course of the vehicle into turns, to features like rain-sensing wipers and the panorama glass roof—everything about its bold exterior design appears to put the 2010 Lexus ES up on its toes.

Its 17-inch, seven-spoke wheels deliver outstanding handling and accent the ES sporty style. Intelligent safety features include SmartAccess keyless entry, intuitive parking assist and dynamic radar cruise control, which helps the driver maintain a preset distance from the vehicle in front.

A voice-activated DVD navigation system recognizes over 100 voice commands and provides voice-activated destination input. Other features of the luxurious cabin include 10-way adjustable power seats, a backup camera, satellite radio, LED interior lighting and luxurious wood and leather trim.

Your ride through the Ozarks will be quiet since the ES features liquid-filled engine mounts and 88 other measures to absorb sound and cancel vibrations.
