Paul,
I know of one "truly public" golf course that better than CH4, and I think it is also cheaper (Bethpage Black).
Mr. Jemseck followed up a few months ago on comments I made regarding trees planted on the greenside of some fairway bunkers. He did not like them any better than I did but consented to them because that's what the Tour wanted. On a couple of holes, they've actually planted trees short of and beyond the bunkers.
It appears that how the big boys play the course has a significant bearing on the property's financials. Maybe they get a lot of tourist play at #4 and these folks want to tackle a course whose reputation (Dubsdread) is consistent with how it plays. Having the pros shoot 20 under probably does nor fare well for the course's image, and, therefore, its bottom line.
CH4 is in my top 5 public access courses, and they don't need to make the bunkers deeper and the greens smaller. Unfortunately, catering to what I like may not be in Mr. Jemseck's best interests. Personally, I'd get a volunteer army of chainsaw wielding golfers and start clearing trees from around the bunkers and some of the tees.
Open up the course, firm up the ground, and grow some lethal rough for the Western Open. If the boys still shoot well under, then I would consider deepening the bunkers and finding new cup placements on the edges and slopes.
