It seems to me that once you acquiecse to the concept of trees on golf courses that have strategic merit, you can find thousands of such trees on courses from mom and pop and muni's to the finest clubs. And, we basically must acquiesce since I'd guess 90+% of courses are basically parkland or significantly treed properties.
The thing about these specimen and nicely placed strategic trees is they don't always remain at their optimum dimensions with growth sometimes making them awkward where they were once nicely proportioned to a specific shot pattern. And, they die naturally, diseased or storm damaged, eventually.
My course has plenty of trees that are mostly well managed and aren't detractive to the round, and on a few holes, might be considered bunkers in the sky that cause you to flirt with them on a sort of line of charm aspect.
But, I still like the wide open prairie best, until you are dying for some shade...
