The term "jeep" is filled with history and connotations in the American vernacular and has become universal for any vehicle that can traverse rough landscapes. The Jeep brand, of course, has been around for generations and when most people hear "Jeep" they think of the Wrangler, the direct descendant of the Willy's Jeeps of the Second World War.
The Wrangler Rubicon model takes its name from the famous Rubicon Trail that runs through the Sierra Nevada near Lake Tahoe in California. That trail, it is said, takes its name from the Italian river (Rubico) across which Julius Caesar marched his armies during the Roman civil war in 49 BC. For as with Caesar's action, once you enter the Rubicon Trail, there is no turning back.
