Deep in the Rust Belt the white collar and blue collar divide has shaped our cities and our states. How did this rivalry change the way we all bring home the bacon?

It's a rivalry that tears us apart every four years, but how did our nation divide into red states vs. blue states, and what happens to the states caught in the middle?

Two underdogs of American culture go head to head to prove how hillbillies and rednecks have shaped our states.

From a prehistoric sharpened digging stick to today's $15-million monster machines, our journey for the ultimate shovel begins in California's borax mines, where the P&H 4100 uses advanced electronics, brute strength, and savvy operators to excavate 170-ton chunks in a single scoop. We travel back to 1835, when William Otis set off an American digging frenzy with his patented steam shovel. And at the Jet Propulsion Laboratory, we kick the legs of NASA's latest Mars Lander: Phoenix. This stationary probe has a robotic arm with a shovel scoop designed to dig into the soil, locate ice, and analyze its properties. Back on Earth, the Hitachi Corporation's 200-ton hydraulic humanitarian shovel is designed to locate and explode landmines in Third-World countries.

It is the bane of every suburban parent and the joy to every school kid. Born in a swirling storm cloud through a process called nucleation, the characteristics of snow flakes are threatened by pollution trapped in the clouds. We'll travel two miles into the sky, where scientists study the inner workings of clouds while perched high on a mountaintop at the Storm Peak Laboratory. Then we'll head to the finest ski resorts in Colorado to discover how they manage the snow on their slopes and how snowmaking really works. These resorts also reside in one of the most avalanche-prone regions of the world. Despite best efforts of experts, avalanches still occur. Discover the new technology that gives rescuers a critical assist to quickly find skiers buried alive when the beauty of snow quickly turns to terror. We'll also go to Buffalo, New York the "Blizzard Capital of America" to watch how a TV Weatherman forecasts blizzards and warns his viewers to prepare for the onslaught.

Got something strange to deliver? From pizza to packages, we'll show you how it's packed, labeled and shipped. Head down the highway carrying gigantic wind turbine blades. See how UPS got China's invaluable terra cotta warriors to a Los Angeles art museum. Deliver luxury yachts aboard a submersible carrier ship. Ride to the track with prized thoroughbreds on their own special jet. Want dinner and a movie? Sounds like a visit to Netflix headquarters and Papa John's Pizza. Ride radical with bike messengers in New York City, and deliver a donor kidney to a waiting hospital. Take a tour of the UPS Worldport hub in Louisville, Kentucky, a mammoth center with delivery docks for 100 jets, and handles 1.2 million packages a day.

It's all around us--so much a part of our lives that we forget it's there. But try to survive a single day without packaging. This episode reveals the astounding technology and ingenuity required to create our packaged world. At a Michigan company that designs water bottles, we'll show you how engineers find their inspiration from a bell pepper. In New Jersey, the makers of bubble Wrap clue you in on their manufacturing secrets. In Texas, workers conquer the challenge of packaging the world's largest crane. And you'll also see how America's military goods and supplies are packaged and shipped by the United States Transportation Command. Other stories include a new easy to open package that's the cure for "wrap rage"--and how NASA engineers packed a fragile humanoid robot for a trip into orbit.

Tens of millions of them all over the world--soda and snack machines, parking meters and payphones, video games and vending machines... and they all use coins--but for how long? Examine the historic one-armed bandits and the 21st century, cutting edge, computerized slot machines that occupy Vegas casinos and get an exclusive look at their inner workings in a never-before-seen factory in Reno, Nevada. Search out some of the wackiest, strangest vending machines on the planet that sell everything from bottles of wine to dog washes. Get a close-up look at the famous binoculars located at popular tourist sites around the world, as well as a unique company that collects and cleans the coins thrown into fountains for good luck. But it all starts and ends in the historic halls of the U.S. Mint, where coins are made and destroyed. Will coins one day become obsolete?

Where in Washington D.C. is the nation's most incredible treasure chest? It's a library unlike any other in the world--the U.S. Library of Congress. Explode the myth that this 200-year-old institution is simply "where members of Congress borrow books." Viewers are taken beyond the magnificent Jefferson Building Great Hall into the secret vaults where more than 600 miles of shelves hold 130 million items, many of them priceless treasures--from George Washington's hand-written diaries to Galileo's first images of the moon to the original camera film of the movie Frankenstein. See how a staff of 4,000 catalogues protects and preserves these treasures and distributes them globally via a new World Digital Library.

If ancient aliens visited Earth, were they responsible for catastrophes, wars and other deadly disasters to control the fate of the human race? The story of the Great Flood sent by deities to destroy civilizations exists in many prehistoric cultures. There are ancient descriptions of extraterrestrial battles that caused wide-scale destruction, and even reports of UFOs lurking in the shadows of recent natural disasters. The Book of Revelations and the Dead Sea Scrolls describe a future apocalyptic battle between good and evil that will destroy our world. Are these ancient texts proof that aliens are hostile and planning a violent return? Or might they be our saviors, ensuring our survival as a species during times of devastation?

If extraterrestrials influenced human history, can evidence of their existence be found in hidden tunnels and caverns around the world? Could a cave in Ecuador contain metallic books inscribed with secrets of alien technology? Was an ancient underground city in Turkey built with alien help... or as a refuge from an alien attack? Rumors of the U.S. military working alongside aliens in a secret base inside a mesa in New Mexico continue to swirl, Native American legends mention strange inner-Earth beings, and recent archaeological discoveries in the Yucatan may point to an extraterrestrial reality behind.

At nearly 14,000 years old, the ruins of Puma Punku are the oldest and most baffling on the face of the Earth. No one knows who designed and built this complex of sophisticated inter-locking blocks, and then vanished. Researchers investigate the ruins on-location in Peru and present new computer analyses. Forensic evidence on the ground, together with local myths and legends, suggest this site may have been designed and even once inhabited by a species of extraterrestrials.

Scientists are continually challenged by unidentified strains of bacteria with mysterious origins. Could some of our most crippling plagues and epidemics be traced to the darkest voids of space--or even extraterrestrial intervention? During the Black Death of the Middle Ages, people reported bronze flying ships emitting a strange mist. As recently as 2011, NASA scientist Richard Hoover published evidence of life in meteorites. Is it possible that ancient aliens--as small as microbes--have shaped human history?

On November 24, 1963, a stunned America struggled to accept the assassination of President John F. Kennedy two days earlier. As tens of millions stared at their televisions that Sunday morning, they witnessed TV's first live murder--the killing of assassination suspect Lee Harvey Oswald by Dallas strip-club owner Jack Ruby. What was seen for 47 hours as an isolated tragedy became one of the most notable suspected conspiracies in US history. And while the Warren Commission claimed that Oswald and Ruby both acted alone, the House Select Committee on Assassinations concluded in 1979 that JFK's murder most likely resulted from a conspiracy. Now, a new development has shaken both sides of the conspiracy controversy. Recently revealed evidence suggests the CIA may have been tracking Oswald and indicates a possible link among anti-Castro Cubans, Carlos Marcello, Ruby, Oswald, and the CIA.

It is 113 BC. Rome is a republic, a small empire clinging to the rim of the Mediterranean. Though it is a democracy in name and spirit, a man there still must be rich and from the noble class to hold the highest offices, both political and military. The system has worked well for three centuries. But now a barbarian horde known as the Cimbri smashes through the northern imperial border. One humiliating defeat follows another, with losses of hundreds of thousands of Roman legionaries. Terror grips Rome and drives her into the arms of General Marius. Though a commoner, Marius has a brilliant military mind. To defeat the Cimbri, he will transform the Roman army and shake the Republic's political foundations to the core. It is a turning point for the Republic. Faced with the savage Cimbri, Rome must decide between dictatorship and annihilation.

Known as "the Mind of the Renaissance", this amazing artist, scientist, and inventor envisioned flying machines, submarines, parachutes, armored cars, and multi-barreled guns centuries before their time. His mysterious painting the Mona Lisa still moves us and his fresco The Last Supper remains an icon of faith. His secretly recorded dissection of human bodies that brought accusations of consorting with Satan led to the early understandings of human anatomy. Against a backdrop of 15th-century Italian opulence, intrigue, and corruption, he navigated through the glittering palaces of merchant princes. The bastard son of a notary in the town of Vinci, Leonardo couldn't even take his father's name, but sensed that he must develop a way to overcome the limitations of illegitimacy. And so a code emerged, a pattern of decision-making that evolved throughout his life, enabling him to become the greatest of men in a time of great men--a mind above all others.
