Make sure you do it courteously and try to suggest other places in the park for them to go. If they still feel like sitting in the middle of the fairway after your warning, there isn't much you can do. Just alert them to your intention to throw that way, make sure they are paying attention and rip one. We have that problem up here with Corbin Park in Post Falls. Most people will pay attention when you alert them but some just don't give a fiddlestick.
I believe many of those outside of the game think "It's just a frisbee, how much can it hurt?
A buddy of mine took his 12 year old niece out to show her the game, and he was standing to the side of the teebox and she grip-locked one into the back of his head. Took 7 stitches to close it up, and she was 12... though we did laugh when he told us about it.
