Each summer in late June, more than 2,000 fishing vessels converge on Alaska's Bristol Bay to await one of the greatest natural spectacles of the north: the annual run of millions of sockeye salmon to their spawning grounds. Bristol Bay is the most productive commercial salmon fishery in the world with an average annual catch of ten million fish valued at $20 million dollars. What follows the fish during the short, three-week run is an altogether man-made spectacle of the highest order: thousands of highly competitive fishermen doing serious battle with one another in their specialized, high-performance boats. Geo will be on deck with two crews as they navigate the bay looking for the mother lode. It's all about getting the fish in the nets. But staying up all night, avoiding collisions with other boats, and keeping the peace with the State Troopers who patrol the crowded fishery by land, sea, and sky just makes it more interesting.
