The crew arrives in northern, California, the land of Giants (redwoods that is). They meet Gia a miller who salvages dead old growth, primarily redwood trees and mills them into usable wood. Not only is she incredibly knowledgeable about trees, but Gia is also a volunteer fire fighter and a mobile mechanic for giant tractors and frontloaders. Gia takes the crew to visit the Avenue of the Giants, home to trees over 3000 years old.
