Count me in for a person that liked it. Also, I was born and raised in CA, and had no idea it was not native; ice plant is up and down the entire coastline from SF to San Diego.
First time I played Spyglass in college, we made a "rule" that you couldn't take more than three strokes out of the stuff; I think each one of us invoked the rule as a result of hitting into it on either #3, #4 or #5. In later rounds, I just took a drop if I didn't think I could successfully make contact with the ball.
Bottom line, golfers always talk about where you can miss a shot. Well, the ice plant was a penal hazard and a definite place to hit away from, and you were conscientious of it when you stood over the ball. Also, it is only on a few holes, and that made it an interesting, short term hazard to me. I wouldn't want to play every hole with it looming, but I wouldn't want to play every hole with the Pacific as a hazard either.
I am curious what the Coastal Commission is going to replace it with, because planting grasses out on those dunes, both on the course and near the homes closer to the ocean, would seem to be non-native and unnatural. Not to mention IMO, it would probably look terrible.
