pmm711: Bushes exist on golf courses.
I am not sure that bushes do exist on golf courses. Certainly, bushes are used on the edges of some course for decorative reasons, others are used to deter certain wildlife, but "on the course"? Not sure about that.
Obviously, trees do exist on the course. Large parkland trees can add a sense of elegance to a course and are often used in situations for a focal point. Some courses even use such trees in the center of fairways to add to the difficulty of the course.
As for the Northern Lights, you can see them more clearly if playing in Iceland.
