Whatever man. I've never seen a disabled individual on a disc course but I don't doubt that they'd have fun doing so. Whether or not they'd be able to actually make it to any of the greens, I question. But having fun is where its at.
I never seem to see anyone on golf courses except old people. But maybe golf is just so mindbendingly complex that it takes a lifetime to master? yeah? Or maybe it's just a sport for people without athletic ability.

Greenfog had a good suggestion with frisbee soccer (ultimate?). But I'd rather just play soccer.
