Two come to mind...
Waverly in Portland, OR got very little play back when I used to live there. Pretty cool course too - Tiger won one of his USGA Jr Ams there.
And I don't think Stonewall "Udder" gets a ton of play. Actually, Stonewall itself doesn't get a lot of play either. It's a second club for many and there are days when you will only see one or two groups on the course.
Shame too, because all three are wonderful golf courses, that any smart member would play at every opportunity.
