David,
Since John was adamant about limiting this to private courses, how about adding Wood Ranch to that list? It's walkable for college golfers (we walked 36 in a college tournament), but even that required a shuttle or two on the course to take you from a green to a tee. There wasn't a bench to be found on the entire property, and it was fairly clear that walking wasn't really something they planned to encourage, if even allow for normal play.
And I think that gets to what you're talking about. Whether the use of carts is built into the revenue model or not, a lot of these are courses that simply would not be built if not for the existence of carts. It's not so much that you had a developer decide his goal was to build a riding only course. It's that the developer had a piece of property on which to build a golf course, and there was simply no way to build a course on that specific piece of property where the average golfer could be encouraged to walk. It was alluded to earlier, but it's tough to find property in the LA area where that's not the case. One could argue that its been a good thing because without cart ball courses, we wouldn't have places like Hidden Valley. The downside to that is that because of the existence of the cart, we've ended up with (what some might call) atrocities like Hidden Valley (and Tierra Rejada which, like you've indicated, is just awful).
