couple of ideas from MSU
Make the game a free event. We have Super Bulldog Weekend that week and its nice to tailgate and hang out and see the game for free. We will have 45 to 50 thousand at ours.
Have a draft. We divide the coaching staff into Two staffs and have them draft players, This is cool cause all the stars are not on one team. Make the losing team clean the stadium after the game. gives them some incentive to play hard
Have an auction where you bid to be the head coach of one of the two teams. Two people who donate the most monety to the RCAF get to be honorary head coaches
