Living in New England for 20 years temporaries were a useful way to keep a course open later and to open it for those occasionally late-winter warm spells that made everyone itch to get out and play, but with a return to sub-freezing temps and additional snowfall still inevitable. I remember going down to Shennescosset or Fenwick on those wonderful days.
On the other hand, I played a prominent Florida course (former PGA tour host) about 30 years ago during its high season with six temporary greens. No mention was made when I booked tee time, no reduction in green fee was offered, and the resort invoked its 24-hour cancellation requirement so I couldn’t get my money back. All six temps were set 150 yards off the tee, mown only barely below fairway height, and were 20-30 feet in diameter with a bucket hole placed dead center. Perhaps the worst golfing experience of my life, spending $125 to play what amounted to a shaggy executive course, but one whose name apparently justified their arrogance.
