Tom,
I am handling the current work at Engineers. We are working on #2 green to rebuild the original shape (slightly softened to allow it to play similar to the speeds found in 1917) after a renovation a few years ago that did not work out. We are also building new bunkers to recapture Strong's original intent of having multiple bunkers set amoung irregular hillocks and native fescues (which had been filled in many years ago). Other than what I have found to be 11 or 12 original greens (most of the others were redesigned by D. Emmett back in the 20's), Engineers was changed significantly by the loss of his dramatic fairway bunkers. We can't restore the bunkers exactly as they were unless the club decides to go back to wooden shafts and old balls. But, his original intent is being brought back.
All golf courses change, as does the game, and it is sometimes necessary to change with it. This is not always a bad thing. If I get frustrated about anything on this site it is that there is at times a prevailing thought that anything done to our older courses is tragic. In the case of Engineers, a significant trait of the original design, the dramatic fairway bunkering, was lost (that was tragic) - we are putting it back in a way that reflects what was originally intended and in a way that will allow the modern player to best be tested by it.
As for greens on our older courses, is it not better to have these greens be able to test players and give them options as was original designed. Sure, the evolution of some of the older greens definitely adds character, but when a green, or a portion of a green, gets to the point that you don't have the option of placing a pin there anymore (when one was orginally intended), you lose the originally intended variety. I think that is tragic. There are many great old houses in our country, but would you live in them today without plumbing or electricity?
I love Engineers for the severity of the greens and its' extraordinary use of the land, but I assure it will be a better reflection of what Strong originally intended when we are done.
