Pros:
It starts off looking like a good idea. The first tee sets right above the river and you shoot across it.
Cons:
At the second pin, i realized that my disc just went over the river and luckily it sailed back to the pin. After further review, most of the pins are near the river which is on both sides of the course, which you don't see at first. If you overshoot, you will loose a disc, i don't see how you would be able to retrieve a disc from that fast current driven river.
Other Thoughts:
Nice spot for fishing but, not for golfing.
