I am going to give my best recollection on topography details of holes 4-6 since there are no pictures available in this thread. It certainly will not be as descriptive as Mr. Doak's input but I will do my best.

The tee box at times could host a gathering of foursomes. It was in close proximity of the 3rd and 17th greens and the 18th tee. A drive off the 4th required a carry of around 190 yards to a fairway plateau. Short of the plateau on the left was a deep sand trap. No more than a 7 iron could be used to safely exit the trap. Balls hit below the plateau, other than the left trap, could be safe in a generous wide fairway. The fairway plateau was around 30 yards in length then sloped down into a mini valley. From there it was a gradual upward trek to the green.
I never caddied for many long hitters but making the green in two was occasionally done. It required a long drive and a precise second shot. There were two fairway bunkers short of the green, a pretty pot bunker to the right of the green, and a long narrow sand trap extending from the back left of the green well down the left side of the fairway. I can't remember the contour of the green but nothing drastic comes to mind.

This certainly deserved the number 2 stroke rating in my opinion. The line of play from the tee had the fairway serpentine sand trap staring you in the face. It was usually not a problem in clearing this trap but two traps further down the right would come into play. The angle of play however favored the drive into the center or left side of the fairway. The fairway was level until about 180 yards from the green then followed a deep drop into another mini valley and then a steep climb to the green.
Long hitters would generally lay up before the fairway descent with a long iron. Go for broke drives required an additional 20 yards or so to avoid difficult downhill stances on the sloped fairway. The second shot to the green, wherever located, required the correct distance to safely hold and stay. Any shot short of the green would roll down a steep descending fairway for about 20 yards. The flag stick would not be visible at that point. Shots short of the green to the left or right of the fairway would catch deep sand traps. To put the steepness in perspective, the grounds crew would hand mow this area with the aid of a rope to pull the mower up and down.
Once on the green there was ample space to putt or if long, to chip back. During tournament play the flag stick was usually in the front right. Besides the danger of hitting the ball short at that pin placement there was a lone massive oak tree about 40 yards before the green on the right. That also caught many a ball.
Hole 6 Road (Modified 2/17/22 To Include 1984 Aerial View) Tee Box Located in Left Corner of the picture
The tee box was in close proximity of the Northern State Parkway. The homes occupying the grounds of the Links can be seen on the east side of the highway between New Hyde Park and Shelter Rock Roads.
This picturesque hole playing as a par five was a stretch. It would have made so much more to a challenging par four. Securing a par was highly probable as long as you kept your drive in the fairway or at least to the right. The fairway noted no elevation change other than a mild climb shortly off the tee. The road to the left in early aerials did not come into play during my tenure. Tall privet type hedge ran between the road and the rough. This hedge extended along the 7th and 8th holes as well. In the late 1960's, there were gated side entrances to the course along this road by the the 6th green and by the 8th culvert crossing. They were used primarily for maintenance supply deliveries. By the mid 1970's the entrances were overgrown.
Short drives off the tee had players face a second shot that could catch three center sand traps about 70 yards from the green. Two deep bunkers to the right of the green were challenging as well. The green was far from flat. Players were encouraged to keep the approach shot short of the flag stick in order to putt uphill. Downhill putts could have devastating consequences. Three putting this green was commonplace.
As a young caddie, not knowing proper etiquette, I was walking around this green while a member was attempting to putt. I was verbally reprimanded in a most nasty way of this infraction. In later years, this member John M. Schiff, became one of my regular loops and a good tipper. His wife "Fifi" was the widow of John R. Fell and a very pleasant person. Back in my day there was an annual tournament at the Meadowbrook Club in honor of Mr. Fell. I wonder if this tournament is still ongoing? Phil Carlucci, would you know?
