Filmed over Chief Seattle Days, which honor the Native American chief that gave the city its name, this episode connects past and present in one of the country's most dynamic metropolitan areas. A tugboat towing timber to a lumberyard at the Port of Everett is a reminder of the industry that built Seattle, but there's no missing the $4 billion urban campus of Amazon, which now occupies 19% of all prime office space in the city. From the air, viewers can also trace the journey of coffee giant Starbucks from its first store in Pike Place Market to its massive world headquarters at the Port of Seattle.

With its famous hills, bridges and Bay, people could spend a day in San Francisco just admiring the views, but this aerial adventure explores the bustling heart of one of America's busiest cities. Gridlocked morning commutes have inspired innovative solutions, from a rebirth of the ferry business to a network of wifi-enabled buses that transports armies of tech workers to Silicon Valley every day allowing them work while they ride. The tech boom is also reshaping the city's famous skyline, which now boasts the second tallest building west of the Mississippi. As night falls, lighting engineers climbing the Bay Bridge show how technology meets art in the 25,000-LED-bulb spectacle Bay Lights, which started out as a temporary work and is now yet another iconic feature of San Francisco.
