Theming is a strong word, not sure I like it. I look at it like this.... If i asked you to draw a pencil sketch of a cat, a dog, a bird, a fish, and a mouse they would all be different completely different shapes and animals, but I bet I would be able to tell that the same person drew each animal, using the same tools and methods. I think the same is true with golf course architecture. A talented architect working with a skilled shaper can provide many different shapes and features, and still carry a certain "look" from hole to hole that makes it all fit.
