Jim,
The green is 75 yards long give or take a few yards. The middle section is all pinnable, as long as you don't get to close to the slopes. The front tier is difficult, and you have to be careful not to set the pin to close to the edge. I would say that there are 3 or so hole locations on the front tier. A front, middle, and back. The back hole location was only used once this past summer, as we were using it as a nursery. There might be one pin back there, but it is close to unplayable.
