OK I'll bite....
I have had a member of the Donald Ross Society solicite work from a club that we were working with. They were asked their opinion on a future change (something we encouraged) while they were up to visit the course.
There currently is a founding member of the Stanley Thompson Society finishing off the restoration work started at another club, because as a member of the society and the club, he felt he was "more qualified" to do the work himself. It took us 10 years to plan and sell the club on the full restoration approach, that we unfortunately never got to complete. We "lost" the job when we insisted on some origional bunkers remaining as they were designed, when the founder felt they should be removed or changed for "playability"
I have had a great experience with the Travis Society (a have been a member since it's founding); and I think that the Ross Society is excellent.
I will not serve on the Travis Society board because I think that would be unfair to other architects, and herein lies my problem with architect societies. If the members want to be architects, I welcome them, it's proabably good for golf; but in a position of influence, they have the opportunity to use their position for personal gain.
I expect a few angry people, or to be told I'm just bitter for losing work, but this explains to all the people why I won't join the Thompson Society despite working with 30 Thompson courses.
