The day of the Ice Bowl game was so cold, the referees' whistles wouldn't work; so cold, the reporters' coffee froze in the press booth; so cold, fans built small fires in the concrete and metal stands; so cold, TV cables froze and photographers didn't dare touch the metal of their equipment; so cold, the game was as much about survival as it was about skill and strategy. On New Year's Eve, 1967, the Dallas Cowboys and the Green Bay Packers met for a classic NFL championship game, played on a frozen field in sub-zero weather. The Ice Bowl challenged every skill of these two great teams. Here's the whole story, based on dozens of interviews with people who were there-on the field and off-told by author Ed Gruver with passion, suspense, wit, and accuracy.
