Had a chance to play Wykagyl. The course is now quite different from what is presented above.
The centerline bunkers on 7 and 11 are gone, for instance. The mowing patterns are adjusted to create significantly more fairway. On 10 a par 5/4.5, the fairway extends well left all the way to the bern. Past the bern, it is uniform fairway left-right until the climb to green, where it narrows, but without the arbitrary curve in on the left.
The Par 3 4th now has a set of bunkers ringing the front, creating an excellent Short. The green is set at an angle to the tee, and slopes strongly back left down to front right.
The bunkers are now rugged with the sand flashing. The fairway bunkering on 12, a par 5, was excellent, and in play first and second shots.
18 is an absolutely lovely finishing hole in it's simplicity. Straight, lots of fairway, and a green banked in the far hillside, ringed with bunkers side and back.
The course now has great internal site lines, while maintaining the parkland feel. The trees give the parkland feel, but didn't unduly encroach on play. From my game, on 5, a slight dogleg right, my shot down the right side brought a tree on the corner into play. However, instead of blocking the shot at the hole, the first branches reaching out into play were well up near the canopy. A low cut would get to green entrance and avoid the green side bunker, but a high shot over the bunker risked being swatted down. For site lines, most of the holes feel self-contained, but in a few place, such as nearing the green on 2, the tree lines end, and you can see through and across 4 or 5 holes.
My comment at the end of the round was that the members must love being able to play this course day in and day out. Every hole had interest. I would have played round again immediately to get another crack at the course.
BTW, is there a better set of courses right next to each other than, running SW to NE in a near line, nearly adjacent, Siwanoy, Wykagyl, Bonnie Briar, Winged Foot and Quaker Ridge?
