Jim:
That's a long story, but the short version is that I did three different routings -- one before I got there, one after a 5-day site visit, and the final one six months later during another 4-day visit.
The first one had to be chucked because I had a few holes in the space occupied by 6-7-8 at Bandon Dunes, which didn't show on my map. There were four holes on that plan which we used in the final version -- 6, 10, 11 and 16 -- plus pieces of other holes. 13 and 14 weren't even on the map; Mr. Keiser gave me that land to work with to make up for the section he had given David off of our site.
The second version had quite a few of today's holes -- 1, 6, 7, 8, 9, 10, 11, 13, 14, 15, and 16 -- and, again, parts of others. [#2 would have been a long par-3 to the landing area, for example, and then #7 would have been #3.] But some of that area was still covered in gorse, so we couldn't see what was going on that well. Mr. Keiser was concerned about the back-to-back par-3 holes and about having all the coastal holes running to the north [#4 was replaced by a different hole running north]. I knew the par-3's pretty much had to stay, but went back to work on the problem of #4 after the gorse had burned. Once we found the green site on #3 (which had previously been under gorse), the rest of it came together pretty fast.
