Let me point out that RTJ did share co-design credit with his son Bobby for the work at Winchester in the greater Sacramento area. Very demanding layout and has been rated among California's 20 best by Digest previously.
One other thing - I've played Eugene and while RTJ deserves credit for what he did with the layout I have always been stunned that many people actually see it as a top 100 course in the USA. Frankly, Trent's work at Mauna Kea is far superior in my mind.
