I think the answer we really need from Rob T - is this a serious sport? If the answer is yes then you have to play. Prom is expensive and dangerous especially for the girls. And as for the graduation stuff, seriously I would do just about anything to avoid anyone's graduation. For my kids its optional. If they want to go fine if not fine. I will be 0 for 2 on my oldest daughters graduations. Graduations are like hallmark holidays. Seriously think about it. Is graduating high school really an accomplishment? No. Its a non event really. This year when daughter #2 graduates I will be on a travel ball trip with son. I skipped my own college graduation and would have skipped high school if allowed!
