I was lucky enough to make a trip down to Eugene last summer - or was it the summer before? - and play with Ari and my brother who lives in Eugene.
Eugene CC is a very strong, solid golf course with an interesting history.
Chandler Egan laid out a good golf course in the '20s, and it was a good golf course for many years.
In the early '60s, the club invited Robert Trent Jones to come take a look at the course and make recommendations about how the course might be improved.
RTJ's advice: You have a very good course here but it would be a lot better if we reversed the routing and put greens where the tees are today and vice versa!
Bingo! There are four or five holes where there were water hazards in front of the tees and not in play. Today these water hazards are in front of greens. Two or three of these are lengthy par 3s and very difficult, and the other one is now a par 5 where the touchy little pitch third shot is over the water to a triangular green with a very narrow front pin area.
There are indeed a lot of big trees, typical NW golf layout, but the corridors are wide enough to demand accurate placement of tee shots.
A very cool thing is the side by side routing maps in the same scale and orientation that hang in the clubhouse. It's fun to see where Egan's routing took the course and how RTJ's routing turned this into a truly championship layout. One fascinating detail is that there were more long par 4s in Egan's routing.
IMHO Eugene CC is a Top 100 course, very good greens, great routing, outstanding conditioning.
