The trees on the left in this picture have been there since 1934.
They've always been an impediment to those golfers who hooked/drew their ball too much off line.
For Mark to claim that they're new is outrageous.
For someone who's walked the course 100 times, he must have confined his journey to the front nine.
Even in the picture he posted, from the green looking back, you can see those trees in the right side of his photo, shown below
The 15th hole looks nothing like his cartoon representation, which is a total fraud.
Go to Google earth or see if a chronological exhibit is available on JSlonis's site, I think it was classicphotos.com and you'll see that the 15th fairway had pine trees IN the left side of the fairway from 1934.
