What do you do when you're responsible for dozens of the highest-tech television cameras on the planet, which must operate outside in 7-degree-below zero temperatures all afternoon on a national TV broadcast seen by millions of viewers? That's exactly the problem faced by Kevin Callahan, an engineer for Game Creek Video, whose five-truck FX HD Production System must brave those frigid temperatures for Sunday's Fox Sports broadcast of the NFC Championship game where the NFL's Green Bay Packers will beat the New York Giants.

The Sony HD television cameras on the shoot are only rated to -4F, so Callahan decided to bring a low-tech device to wrap around all those millions of dollars' worth of gadgetry. What did he do? On the way to Lambeau Field out on the now-frozen tundra, he stopped at every Target store on the way, buying up all the electric blankets he could find. He didn't forget about those human camera operators, either: "We know that once the game starts the blankets will be for the camerapeople as much as the camera,” he said.
