Tony -
I have not played JI West in the last two years, but played it close to annually over the prior 10 years. I recall the series of hurricanes that hit FL in 2005 or 2006 devastated a lot of the vegetation on the West course. Prior to this "clearing", one always had the sense of being on a remote golf course, despite being in the middle of a very populated area of the East coast. After the storms, particularly around the 4th-6th holes, the feeling of solitude was gone and you could see neighboring "developments". While this did nothing to impact the architecture of the holes, I felt it removed some of the feeling of remoteness and did affect the "aura" of the experience.
Did you happen to see any of the the abutting developments? I am heading back there in April and hope that much of the vegetation has grown back in the last couple of years.
I think the course has great terrain, particularly for a FL course, and the green complexes are fabulous. It can be a very tough course, but is great fun to play. The 17th and 18th holes are really fun risk/reward finishing holes.
