Cliff / Mike S:
I very rarely think about my ratings for courses in terms of that "100 mile" test I suggested for a course which was rated 7. I just think in terms of other courses I've rated. Looking back into The Confidential Guide, I rated Wannamoisett a 7, and Metacomet and Newport a 6. I couldn't see Misquamicut as higher than the latter two, even though I am obviously not a huge fan of Newport, either.
One of the reasons I don't really use the 100-mile test is because 100 miles is relative to where you are. If you're in Montana, damn right you'd drive 100 miles each way to play Misquamicut, but of course you can't. I actually grew up almost exactly 100 miles from Misquamicut in Stamford, and on reflection, it WOULD be worth driving 100 miles each way from there to play it ... but to do so would have to choose it over every course on Long Island, and drive past Yale and Fishers Island en route. Maybe I would feel differently if anyone had actually invited me to have lunch at their beach club!
I'm surprised there are not many good photos of the course, considering Larry Lambrecht is a member at Misquamicut.
