I cannot seem to find my notes for the 1995 US Open, but I do not believe much changed between the 1986 and 1995 Opens. Here is a comparison between 1986 and 2004. There has been some lengthening of the 3rd,4th and 8th holes. There is still some room to lengthen the 2nd,6th,10th,14th (now that the garages have been taken down) and 15th holes. Of these, the 2nd and 15th holes would be my priorities.

Some fairway width has been regained such as 12 yards to the left of the 8th fairway. There is an ongoing restoration of green space that is resulting in fascinating pin positions near fall-offs and bunkers that are being brought back into play. To date, the 6th,12th,13th and 17th greens have been done exceedingly well. A few greens will be done each year. I believe the 5th green is among several under consideration for next year.
