Garland,
I disagree with many of your points. First of all, to focus on a golf course based on walkability alone is illogical and in doing so missing the point of the golf course altogether. The main concern when evaluating a golf course should be how well the course is routed based on the property given, and how well and uniquely each of the holes were designed.
In this case, Harbottle got the most out of the property and produced some wonderful golf holes. The fourth is a great par-3, for example, and par-4 holes such as the 7th, 8th, 14th, and 15th are also very good and use the land as well it could have been used. The tenth and eighteenth are both very good par-5's, and with the exception of the 12th, there isn't a bland hole on the golf course.
Harbottle used the best features of the land to design some really good holes such as 14 and 15, and when the land presented a challenge, such as the 5th and 17th, he still created solid and unique golf holes. As such, given the severity of the terrain, he did a good job routing the golf course, getting pretty much everything he could out of the terrain.
As far as walking goes, there are going to be difficult green to tee walks on any golf course with terrain that severe. The walk to the second is not nearly as bad as you say, nor is the walk to the third, fourth, sixth, and seventh. Not to say that they are the shortest and flattest green to tee walks, but with the terrain Harbottle had to work with what else was he supposed to do?
I feel like you are being far too nitpicky of certain things and need to evaluate the golf course for just that, the golf course. If all you base your review of the golf course of is on it's walkability, then you surely are missing the point.
