Even better: Refuse to attend the game. Football is religion in the South, and a half-empty stadium on Friday night will send major shockwaves through the community.
Let the Superintendent and the School Board president know why you're not at the game. I promise you, if enough people do this, it will get everyone's attention.
A school's ACT scores may be in the tank, but that's no reason to panic. Boycotting high school football games... that's another matter entirely.
