Some very interesting responses so far.
The greens could be big Tom, multiple pins positions, humps and hollows, run offs and all that.
Like it David, pitch-n-putt more interesting than conventional golf.
Lots of other Goat Hills/Shelter Islands around as well Jeff. Many a course, often of the more rural and rustic variety, just 9-holes, built circa 1890-early 1900's but never extended when the longer travelling ball came into being.
Indeed maybe what I've described in the OP could become almost by default the future of golf if the game continues to go down the longer distance avenue but land to extend courses stops to exist. Food for thought?
