I went to 6 years of high school football games because I had a child, niece or nephew who was somehow "involved" with the game. (No football players, but band, cheer, dance team, etc.) Everyone I went to see has graduated, so I don't go anymore.
If, in the future, someone I love is "involved" and I am able, I'll definitely go to support them. However, I doubt I'll go to another high school football game till then.
