Ian,
At the present time, I couldn't answer that question.
It is possible that he perceived that very little in the way of reclamation or new projects would be undertaken, but, I had heard that there were a number of small projects on the agenda.
Hod,
I'm not familiar with Larry Brown.
Scott,
Sometimes the thought of semi-retirement or a pre-retirement change to a warmer climate is appealing, especially if the offer is lucrative.
Other times the arrival of a new regime or green chairman can precipitate a desire to move on.
In other cases, certain supers are like nomads or hired guns, they arrive to correct and/fix a bad situation, and when the work is done after a few years they move on.
Other times a combination of the above factors causes a move, or the super's health, his wife's health or yearings, or the desire to return to his native locale can have an influence.
Supers at "NAME" courses may tire of the pressure or the work and pressure associated with getting a course ready every year for a big event.
What ever Karl's reasons, he did a great job, not just for NGLA, but for all of GOLF, and we should be thankful and wish him well.
The next question is:
Who will be the next super at NGLA ?
