Claustrophobic probably wasn't the right word, but it sure does look cluttered. Take this shot for instance:
You have utterly gorgeous bunkering that's completely covered up and hemmed in by trees. Instead of having a hole that would look unlike anything else in the area with those blinding flash-faced bunkers, you instead have a tree-lined hole that looks like it could be on any course in Cincinnati.
It's obvious from this photo that 5 sits in a nice setting, but wouldn't have a ton more panache if you got rid of all the trees surrounding it?
And I agree that this bunker looks wonderfully intricate, but it just feels out of place with those conifers so close behind it.
I don't usually throw fits about tree clearing, but this just seems like a course that has obviously been overplanted. It looks like it could be something really special and certainly unique to the area if we don't count NCR in Dayton, but the tree management is just completely incongruous with the overall shaping. Big, flash-faced bunkers demand wide corridors to stay in scale. They're sharp features and biomechanically, they draw the eye and make it move across the land. For that effect to really work, though, the landscape needs to accommodate and encourage that eye movement. Coldstream looks like way too many of its most eye-catching bunkers are covered up by trees. While I love big specimen trees on a course as much as anyone, I hate to see them neuter what should otherwise be really commanding, beautiful, and intimidating bunkers and zap a lot of the character out of the course in the process.
