Shooter & ForkB,
# 3 at NGLA = Great:
I would start with the mulitiple option tee shot.
One is presented with a very wide fairway, partially protected by a diagonal, short left to far right bunker.
The risk/reward on the tee shot is fabulous, the options unlimited.
Hit it left, requiring a shorter carry over the cross bunker, and you have a longer shot, over the alps, with a longer carry required. In addition, bunkers and rough can also catch an errant ball.
Hitting it straight requires a longer carry, but if you don't hit it far enough a downhill side hill lie confronts you. Hit it longer and you're rewarded with an uphill lie for the shot over the alps, but care must be taken not to hit it too long into the bunker of rough.
If you can hit it right, over the long carry and you can be rewarded with TEPaul's turboboost, up the slot, leaving you a shorter shot, sometimes leaving you with a view of the right side upper green. But, that requires an extraordinary shot, and should you miss it, the woods, bunker or heavy rough increase your challenge.
The second shot is great, and so dependent upon your lie, based upon where you hit your tee shot.
The need to get the ball airborne, the need to keep it airborne weigh heavily on your mind as you stand over your shot. You are also somewhat worried about direction and distance. While distance can be ascertained, direction remains questionable despite a directional indicator, which is more general and dependent on angles then specific.
TEPaul's next favorite "greens within greens" is the next destination. You, horribly, mistakenly indicated that the green should be smaller. The genius of the design is the need to hit to the "green of the day", and the diverse challenge offered if you should miss it.
# 17 at Prestwick, while wonderful, is a pitch and putt hole.
# 3 at NGLA is a big, expansive, longer, more demanding hole.
At # 17, hit a good drive, and the balance of the hole presents a diminished challenge.
At # 3 at NGLA hit a good drive, and the challenge just begins. Hit a good second, and substantial challenge remains.
# 3 at NGLA is great because it tests your game with EVERY shot you hit, until you have holed out.
That is what makes it both unique and great.
