Endurance.  It's a big asset in hockey, and the Havre Ice Hawks high school hockey team proved they had plenty.  After playing a game in Great Falls on Saturday morning, the Ice Hawks traveled back to Havre and took on the Billings Bulls in a makeup game Saturday night at the Havre Ice Dome.  And while the Bulls had blanked Havre in two games in Billings earlier this month, Ice Hawk's senior Kyle Miller made sure the story had a different ending on Saturday night.  Miller racked up six points against the Bulls, including a hat trick, scoring three goals, while also assisting on three goals as Havre won in a highscoring affair, 9-6.  Havre jumped out to a 4-0 lead after the first period, but Billings rallied and got within two goals at 7-5 early in the third period.  But Brandt Miller, who also scored two goals and had an assist put Havre back up by three points and the Ice Hawks cruised home from there.  Havre also got goals from Danny Roe, Tyler Miller, Jon Austin and Jesse Majeres, while Roe, Majeres, Brandt Miller, Justin Jensen and Dillon McLain also had assists for the Ice Hawks, and goalie Willie DeVries saved 24 shots between the pipes.  Saturday night's win came just hours after the Ice Hawks lost in Great Falls 7-4 to the Great Falls Americans.  In Saturday morning's game, Roe had a goal and an assist, while McLain, Brandt Miller and Tyler Miller added goals, and Brayden Grimson had an assist.  In the loss, backup goalie Gareth Bernard stopped 14 shots on goal.  Havre also skated to a 2-2 tie against the Americans on Friday night.  DeVries was brilliant in goal for Havre, stopping 34 shots against a potent Great Falls' attack.  In the tie, Havre got a goal and an assist from both Roe and Brandt Miller, while Austin also assisted on a score.  The Ice Hawks (10-4-1) are back on the road this weekend with a pair of games in Bozeman.
