I've been meaning to put together an eclectic 18 from Boston-area layouts I've played.
Out of the holes profiled, and that I have played,
13 at Salem is a slam dunk
18 at Essex is a great candidate among many other great #18s
9 at Whitinsville is a great hole (a Crenshaw favorite) among many other great #9s
7 at Concord CC is not the best out there (#2, #4, #10, #16?) but a good hole nonetheless
3 at Kittansett could be a slam dunk, a great hole.
I haven't played many of the others, like RICC, Wellesley, Bellevue (sleepy 9-holer), The Ridge Club (two holes in this gallery??, weird), Pine Brook, Marshfield, Marlborough...
And my fellow club member Cy Kilgore recommended the 15th at President's, a polarizing hole if there ever was one. It probably isn't the best hole at PGC, but there is certainly never a dull moment when one reaches that hole, and it witnessed a double eagle by a member last year in the Norfolk Co. 2-ball. My partner in this event last year shot a 64 on his own ball (5700, par 70), and we had 61 as a team, finishing T-4th with 68-61-129.
Dan, I was also perusing the Butter Brook website today, as the wavy-edged bunkers are certainly a unique thing for MA public golf, if not in other places....I will have to get out there sometime soon as well.
