What amazes me in this discussion is that you have some ideologues who view carts in a one dimensional manner -- to wit, they have no place period!
That's all very nice but the realioty is that the driving engine for many clubs around the country is the selling of land / homes and the use of the golf cart in maximizes the value of adjacent property when building the course. Again, the idelogue type will say "damn the houses and the innane routings and just build the golf course." Again, that would be nice but sometimes the financial numbers don't compute with that reasoning.
Yes, I'm a firm advocate in walking -- I think the rule at Bethpage Black that ALL players must walk is a great one. Ad, I commend many clubs (some of them public -- like Whistling Straits, to name just one) that also mandate "walking only" as a positive development. Kudos also to the many private clubs around the USA that actively promote walking through a caddy program.
But given the dearth of quality land in populated areas and all the attendant rules / regs of federal, state and local environmental groups it's amazing much golf gets built at all. Unfortunately, because of all the hoops that developers must jump to appease the real and sometimes unreal objections the
cost to play only increases.
I don't like to see players (especially young golfers) using carts -- especially on flat as pancake courses when they have the physical health to do so. I am a walker and have been since my dad introduced me to golf over 30 years ago. But, there are a number of people who simply tout the idealistic version of what golf should be and usually diss the realities the industry is facing today. Walking is making a comeback and many courses are using that element as part of their branding / marketing campaigns. I think that's great and more should do so.
However, when I review courses I don't hold it against any course if they mandate cart usage. My only issue would be if cart rides to nearly every hole require some sort of absurd trek that goes on and on. Given the nature of property available today and the encroachment on wetlands, endangered species and severe slopes, to name just three issues, the use of carts is a tool that will assist with future development and course construction.
When people talk about slow play you are really adding another issue unrelated to the question at hand. It's always been my belief that management at any facility are the ones responsible in keeping things moving. Having idiotic rules that forbid carts off the cart paths (par-3 holes an exception) is one such stupid rule because it simply drags play -- especially on land with severe slopes that require players to drag several clubs to each shot.
Mark, I don't know if the precise numbers of courses is 1/3 of the total as mentioned by TF, however, I do know it is possible for golf development to incorporate cart usage without fundamentally distorting the key elements that make golf such a grand game. More and more development, from what I see, is moving in this direction because they realize how poor planning can ultimately impact their specific project and ultimately their bottom line.
Hope this helps ...
