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.
