Every once in a while someone gets on here and asks what are the new design concepts exclusive to the US, or post WW II, or of the modern (with definition of modern) age. The thread originator is usually a newbie, and all the old hands on the site shout him/her down with "There are no new design concepts in golf!"
Well, I may not be the greenest greenhorn on this site, but I certainly am not as far travelled and experienced as many, so I have an excuse if it turns out the same answer applies.
Are Inverted Bunkers as, for example, seen at Las Palomas Links #6 an original design concept?
