Interesting, 11 is one of my favourite holes. Yes the approach is extremely narrow and the trees guarding the green could perhaps be trimmed a bit, but I like par 5s that make you really think about placement of the second shot to setup the third and this hole certainly does that. The opening to the green is very small but if you miss placing the second by a bit there is the challenge of perhaps going over the trees or working a slight fade or draw depending on the day's hole location. I enjoy the challenge.
Kalen, first off I agree completely that photos can make most holes with tall trees appear much narrower than they are, that is the case with Sahalee for sure. When I posted my profile of Royal Colwood a couple of years ago I received some of the same comments and, based on the photos, both courses look extremely tight, much tighter than they are in reality.
I have played both MW and Sahalee several times and don't think there is a comparison, I do not think of MW as a narrow course. Now it has been several years since I was at MW so things may have grown in, but I think of that course as being set in the trees, but not necessarily being tree lined. Sahalee is certainly tree lined.
