RE: The cart path, another photo shows an asphalt path well shaded by trees, and yet other photos show the path well hidden. My guess is the two lane dirt road is a maintenance or leftover construction road that will eventually be gone.
As to the hole, while there are several plausible design scenarios y'all can debate, I think all the ones in the photos surely have design merit and look great.
Aaron, I am not sure what your beef is with the trough - look at the right side and you can see a ridge carried across there. Rees cut that ridge for vision, and the trough because he wanted a cape style bunker of sufficient depth to be a penalty. He may have needed the dirt somewhere else as well.
Had he left the ridge, opting against his (and most gca's and golfers philosphies) he would have ended up with a blind shot and no known to the golfer tee shot options. And, the hole wouldn't have been nearly as attractive. So, why rail against cutting a hill for vision on "general minimalistic principles" when in fact he created a very nice hole? I really don't understand, but am willing to listen.
I don't know if many can carry the bunker, but the layup option seems far enough back to make a difference, even on a short hole. And, if not, nothing wrong with a sucker punch tee shot!
