I knew that comment would draw up more discussion!
Greg, I agree with you. Garland hit on my point with his comment regarding courses with five or six sets of tees (and i know tees boxes are only part of the equation). Modern designs have adapted to new technologies by providing what some people think is an overabundance of tees boxes on each hole. I see these additions as the opposite, a way for the architect to bridge today's advancements with the game of the past. As Garland also mentioned above, youngesters are hitting the ball longer. That wont be a trend that goes away. While most architects attempt to site these multiple tees to meet the varying skills with equal strategic play, not all courses succeed. The ones that do, in my opinion, will be the ones that serve as the model going forward.
Embrace the technology rather than designing for the sake of beating it....moving forward, not backwards...
P.S. I also agree that there are others ways to adapt to advances. Adding tee boxes is not the only answer.
