2003: The NHL heads outdoors for the first time in its 86-year history. Before a record crowd of 57,167 fans at Commonwealth Stadium, the Montreal Canadiens edge the Edmonton Oilers 4-3 in the Heritage Classic .

The celebration of hockey begins with a game between alumni of the two teams, including Wayne Gretzky from the Oilers and Guy Lafleur from the Canadiens. It even has a still-active Mark Messier of the New York Rangers, a member of Edmonton's dynasty in the 1980s. He gets permission from Glen Sather, Rangers general manager and the coach of Edmonton's alumni team, to play in the game.

The big crowd sits through bone-chilling cold to see the Oilers alumni win 2-0, then watches the Canadiens hold off the Oilers in the scheduled game. One player who comes up with a unique idea on keeping warm is Montreal goalie Jose Theodore, who comes out for warmups wearing a toque (wool cap) atop his mask and keeps it on throughout the game.
