If you pump your disc too hard it has a good chance of getting taken by the wind or going into the river behind the pin. The river is always cold and moving fast. It get pretty deep in the spring.

When the wind is blowing, it's nearly always blowing from right to left once you crest the hill, so take that into consideration. While a RHFH or LHBH throw will give you the cleanest line, any turn will run the risk of exposing the bottom of the disc to the wind and can easily carry the disc into the river on the left. Also, the pin on the right is actually 18's pin. 11's is straight ahead at the edge of the river.
