Does a medical situation count as a good reason for not attending? For nearly three years, I have been discouraged by my doctors due to the strain it would put on my body - climbing up and down stairs and the elements are difficult. Not saying this is an excuse for everyone. I would love to attend a game.
One other note. Taking your thirteen year old son to a Redskins football game is bonding. Taking your son to a Cowboys-Eagles game is abuse.
