Replying to Shooting A Glow Ball Tournament

I take photos for all the local golf tournaments in my town. The head pro asked me if I could come to their glow ball tournament to shoot. For those of you that don't know glow ball is just golf where the balls have glowsticks in them to make them glow. What I don't get is what am I going to take pictures of? It's just gonna be dark. So basically I'm looking for ideas, +k to all that help out. I already have one idea, just doing a long exposure so you can see the balls path when it's hit. Any other ideas will be greatly appreciated. Thanks a ton guys.
