The stand alone golf course is becoming a rarity. Increasingly golf courses are just one item on an amenity package for a high end housing development.
This has led to some vast distances between holes that often requires driving through neighborhoods in search of the next tee box. This phenomena has also forced some modern courses to ban walking and make use of a golf cart mandatory.
The truly “walkable” course design is usually an older course built in the last century and sadly they seem to be going the way of the 3 iron.
