Philanthropy water war idea

[scoobis]

I was just recently appointed my chapter's philanthropy chair and given the responsibility of creating a philanthropy event. My idea was to have a capture the flag game on our campus's intermural fields with squirt guns and super soakers where several houses both fraternities and sororities are on a team and compete against other teams consisting of Greeks. The event will be entirely greek because i think it will be easier to organize teams by houses instead of dividing dozens of randoms. I was thinking of having all of the proceeds go towards a veterans foundation, but i'm not sure if a mock war would be insulting or not. I'm not sure how much to charge, how to publicize etc. so if you have any suggestions, criticism, or alternate ideas i'd appreciate it.

Thank you,
