Carts have made at least one contribution to golf. They have enabled courses to be built on severe terrain that could never accommodate a walking course. There are some fairly decent courses, especially in the mountains, that simply would not exist if carts were not available.
I am not so much offended by carts as by poorly placed cart paths. Many courses here in the Sandhilld have cart paths that are completely unnecessary. Pinehurst #2 has carts but the "paths" are natural sand and are in play. I recently played Old Town, an old Perry Maxwell course in Winston-Salem. It is built on rolling terrain and many members use carts, but there are almost no paved paths.
Let's face it. Carts are here to stay. But, maybe we can influence clubs to limit the use of paved paths and to locate them so that they do not effect play.
