On the micro point of rating the experience of a longish cart drive just to get to a practice paddock and first tee, I also agree that in such a landscape, it is actually a great part of the experience. The ride out to the tee at SH or DR (I was only there during construction and didn't play it) but the ride is part of the anticipation. They are pleasant rides and build a sense of place. The ride is a sort of journey in and of itself, setting the tone where you are leaving the hub of a clubhouse and activity, to engage in the walk (or cartball ride) into a more isolated and unique place.
Sutton Bay original was very similar in this regard. While Sutton wasn't a mandatory cart, it was pretty much essential for all but the fittest. Yet, the ride out there seemed nearly a mile. And, there was a bit of a ride from 18 back to one tee. The ride was a very nice journey through that native land as well.
Getting older, I know I would walk DR until I couldn't anymore. It would be great if narrow but firmish 3-wheeler cart cuts from green to tee can be placed unobtrusively just to keep the old guys walking a little easier with aid of the push carts. For most of us older guys it is the weight of the bag combined with the slope that is tough on back and knees. A three wheeler doesn't completely cure that, but it helps and keeps the player with just that much longer of a time in life to enjoy the assisted-by-cart walk. But, I think it is wise to have the power carts available for those that just won't or can't walk, because it would be something of a unnecessary deprivation of the golf spirit to restrict older or unable golfers, who can otherwise still hit the ball if they can get to it, thus depriving passionate golfers who would travel so far to experience this unique experience and is just wrong soley because the walk is no longer physically possible.
I get the notion of a modern trend moving away from a walking culture, when it comes to the issue of modern open to the public normal sort of terrain available in various regional venues where golf is developed. But, these remote locations in unique terrain have a different sense of place, and one goes for the solitude and remote long views, etc, paired with the unique golf that can be routed and designed within them. So, we need to cut the notion that unique places like this somehow diminish the 'golf walking culture'. They enhance the spirit of golf no matter how you get from CH to 1rst tee or make an 18 hole second round turn, or just need the cart to make one or more rounds in the first place.
If you made your way to Hooker Co., Holyoke, Valentine, Bandon, etc., to experience these unique offerings of golf and you ride in some fashion as part of the situation, you haven't diminished or added to a bad trend in the golf culture, you have added to the totality of the world wide passion for golf and the spirit that beckons those so motivated to embrace the game.
