Party For Teenage Bot

My son is turning 16 in December and I want to have a unique party at the house. We live on a farm with a creek and have had bonfire parties before, but want to do something different. There will be boys and girls there. Usually, the girls go home after the party and the boys spend the night. Someone help me with some ideas. I am drawing a blank. Thanks in advance.
