Each spring we had our annual Kick in the Grass, a soccer tournament. It was pretty popular with the fraternities, the games were fiercely competitive. We always had a good turnout and raised a couple thousand dollars or so. Chapter members signed up to "coach" participating fraternities. We'd have a dj and tons of food and water for the guys. We got lots of sponsors from the community. One year we incoporated a skit night where each fraternity would present a skit and the seniors would judge. It was always a lot of fun for us and for the guys. Our philanthropy events could only last two days max according to our local panhellenic rules.
Good Luck with your King of Hearts....I can't wait to hear all about it
