Years ago, I failed to get a commission, and the reason I was given was that they were hoping to get RTJ's last course.
What's interesting for us gca buffs is, as TD alludes, determining what was the last course an aging architect had a major influence on. Examples may include RTJ and the Alabama Golf Trail, where Roger Rulewhich is widely known to have done the work, and who knows about Pete, who had younger associates or sons building at least some of the courses with his name on it.
In other words, I would be interested in the last course where he moved to live on site to see if I could spot the differences. For that matter, I think I can spot differences in Ross courses built by his Chicago office over his NC one. Others would know better, but was there a Ross course other than Jeffersonville NC that might have been his last?
On the other hand, in this environment, with most gca offices downsizing tremendously over the last 10 years, it may very well be that for most of us, approaching, at or just past retirement age, some of our last courses had more of our own personal touch, not less.
Overall, a pretty uncomfortable discussion for a 66 year old gca, LOL.
