All the sand.
If you look at old photos of many golf courses, sand, not turf was abundant in many areas, especially at the green sites.
GCGC, CPC, Pebble Beach and others had vast sand expanses.
Why have they shrunk or disappeared ?
And, when discussing restorations, why isn't the restoration of those features on most agendas ?
Which is easier to maintain sand expanses or turf ?
Are carts the culprit ?
