Tom Huckaby,
I have a limited amount of time and I really can't take on more pupils, but, I'll make an exception.
One only has to examine and analyze the impact of automated irrigation systems to see one of the first causes of narrowed fairways.
Maintainance costs are another factor.
Increased distance, TV, the PGA Tour and Majors are another.
Didn't you watch the last few PGA's and U.S. Opens ?
Winged Foot, Baltusrol, Bethpage, Torrey Pines, ANGC, Oakmont and Shinnecock have all narrowed their fairways, as did Merion.
Torrey Pines is still in California isn't it ?
How about Riviera ?
At almost every local course I've played, fairways have been narrowed versus their original configuration.
To NOT SEE AND RECOGNIZE THAT TREND would place you squarely in the Ray Charles school of observation.
The trend is undeniable.
