Carts dumb down a golf course from several perspectives.
Carts mean cart paths, which mean presenting a blatantly artificial and ugly surface into a natural environment. A carpath ALWAYS detracts from the visual appeal of a golf hole if it is visible in any way. A cartpath takes away from the natural, rugged element of a golf course.
Taking a cart means zooming past important land features and architectural features that are critical to understanding any golf course. A golfer who rides always misses something important about the golf course. Walking a course will always give a better feel for the terrain and, more importantly, the strengths and weaknesses of a golf course routing.
Carts take away from the adventure of a golf course. I have played several courses this year, including Galloway National, May River, Lederach, Morgan Hill, and Inniscrone, which are modern golf courses routed with cart golf as a some sort of crutch or necessity. However, each of these courses was a true adventure to walk and play. From the walk through the live oak forests of May River to the long, heart rate-raising hikes at Morgan Hill, walking was a part of the experience that made the course a blast to play. Morgan Hill was especially fun to walk, as it really made me appreciate the way the routing traversed the rugged terrain. After diving downhill on holes 10-12, the course climbed several hundred feet from 13 tee to 15 tee. As I reached the 15th tee, I felt as if I had completed a mini-mountain climb, and it only enhanced the experience. Golf becomes more than a walk in the park on these types of courses, turning into more of an engaging journey of self-discovery. If I had not walked any of these courses, all of which have routings that give players an excuse to ride, I would have missed an essential aspect of golf.
If you want to get away from your wife for four hours and drink some beer, go to a strip club. If you want to have an adventure, observe the land and architectural features of a golf course, and engage with nature, play golf and walk.
