I thought McBroom did the work on 18...it looks like his bunkering. My guess is Moote did 17.
17 and 18 are so out of character from the previous 16 holes, AND each other...they really detract from what came prior.
10 is a standout (very St. George's-like in its fairway movement and approach to the green). I'm also very fond of 12. Bumping an approach to a front hole location is good fun.
In regard to trees, I'd agree with Mark that generally the trees do not interfere with play...I think Frank's perspective comes from his 'slinger-hook' that he needs to start well outside the centre-line
I was impressed by the massive tree removal around some of the greens, including 2 and 15, two of an excellent set of par 3's (what else to expect from Thompson...)
I'd have Burlington in the top 75 in Canada.
