Joel-
I know you play the OC Lake on a regular basis. As someone who has played there half-a-dozen times a year for the past 20 years, I would submit the Lake for your list because of:
1) The sloping contour of the property site and the sloping fairways that produce so many side hill lies.
2) The swales that seem to run in front of so many of the greens (#2, #6, #9, #12, #14, #17, etc.) which make run-up shots difficult and often lead to pitches off downhill lies to uphill greens.
3) The uphill walk from #17 tee to #18 green and then to the clubhouse. After the course has beaten you up emotionally, it exhausts you physically!
4) Last but not least, the trees, even though there are a few less than there used to be.
I think the "physical" character of the Lake is perhaps its most distinctive feature.
