Hearty fans bundled up to take in the action as the Calgary Flames '89 alumni team took on former players from the Montreal Canadiens on Saturday afternoon at McMahon.

The game was only 2 periods and the Habs won 5 -3.

Before the alumni action began, the current Flames and Canadiens held practices to prepare for the Heritage Classic on Sunday.

The Flames posed for the official team photo in their game day uniforms and toques and then changed into practice jerseys to test out the outdoor rink.

For many it brought back memories of childhood games outdoors.

"Literally when you're younger, now we're probably a little bit softer, but being minus 15 and a blue sky was a great outdoor rink day," said Flames Captain, Jerome Iginla.

It may have been cold for the Flames but it was even colder Saturday morning when the Canadiens took to the ice. The sun was so bright that many players had to wear black patches under their eyes.

"I think it looks pretty cool," said Mike Cammalleri, Canadiens winger, "I was gonna wash it off and I thought no let's go with the interview and look pretty tough."

The gates open at McMahon Stadium at 2:00 on Sunday and game time is at 4:00 p.m. MST. Fans are encouraged to arrive early to avoid security lineups.

There won't be any public parking at McMahon Stadium so the best way to get there is probably by LRT to the Banff Trail CTrain Station which is located across from the stadium.

41,000 fans are expected to pack the stands even though the forecast is calling for temperatures around -8.

Fans should dress warmly and are reminded that thermoses, coolers, flasks and alcoholic beverages will be confiscated if people try to smuggle them through security.

Calgary's Heritage Classic will be the first NHL regular season game held outdoors in Canada since the Edmonton Oilers hosted the Canadiens at Commonwealth Stadium on November 22, 2003.
