Not to totally change the thread to "Granite Links," but I actually work in Batterymarch Park, about a half mile from the GLGC entrance. I've played the original 18 several times, and it is quirky to say the least. There are some great visuals, views of the city, aesthetic bunkering. I have to say that I do not think it is particularly playable, and interestingly enough, I think it plays much more "normal" (if there is such a thing at GL) from the back tees. I played the whites in an outing, and many of the holes required iron tee shots, etc.
I have not played the new 9 ($65?), and perhaps it compliments the original 18, but I have heard it's much like the other holes. I hit balls there quite a bit, and it is a nice spot to whale away and putt and chip. But, if you are looking for fun, President's is the place to be.
Alas, the golf course is much better than what it was before...a place for Whitey and his goons to ditch tainted cars in the quarries. They certainly play up the "closest course built to Boston in 30 years" angle, and use it to charge a hefty fee.
