Divisional rotation makes rivalries a little hard to come by, but based on proximity (roughly 400 miles, the closest team to Montana) and being in the same division this season, I would list Regina Elk as a rival for Great Falls. The teams finished 6 points apart last season with Regina at 54 and Great Falls at 48, both teams snuck into the playoffs but were eliminated in the first round. This season the teams are 3 points apart at the half way point, Regina at 39 and Great Falls at 36.  Call it bad luck or whatever, about being in the same division as the two championship teams last season, Regina and Great Falls are fighting for 3rd place.  One of these two teams will miss the playoffs, most likely with a winning record.  Great Falls is currently 3-0 against Regina with one more matchup remaining this season, but Regina continues to hold the higher place in the division for the moment.
