Question:

Asking for ideas on party?

I am graduating this month. My major is in graphic arts. To celebrate I am a hosting a potluck and party in the park for my family and friends.
Any ideas to have games to have fun? I've already considered having a chicken pinata and water balloon toss.. Any more from you creative people? Thank you!
