Peter:
This HAS been discussed before, to great length and heated debates.
"It's a difficult process that needs at it's core, an extensive research project, before any goals are determined, or worse yet, pre-determined"
This is Pat's best statement and the one I agree with the most. I don't necessarilly agree with his view that "tweaking" is some form of 'modernizing' but he doesn't elaborate, nevertheless, IMO, tweaking can simply mean minor shaping and I mean very minor to a bunker to recapture its original character, or restoring a putting surface to the corners or to reinstate a false front, or an intersting roll-off next to a bunker.
No matter what, it is essential IMO to perform the research to learn and educate the members regarding what they have now and to document how it has evolved over the years. They may also discover interesting information about the original architect that helps to guide decisions. Somewhere, sometime, someone needs to and will make decisions about what to do, it is inevitable...right or wrong, so education will go a long way toward assisting them to make the best decisions for the club and the course. Additionaly, some practical/functional decisions will need to occur...drainage maintenance/agronomics, pace of play and again educated minds will have a better chance to determine a balanced approach that satisfies historical issues/values as well as present day elements.
It has been documented on this site and by other respected architects, designers and historians that rarely does a 'true and full' restoration make sense for all involved. Even so, during the process of research, the hopeful discovery of drawings and especially construction or soon after opening photos will tell much about what was really there. The more material the better, so decisions are NOT made solely based on one form of historical data. Only then, IMO can the club properly assess their best move.
I think it is a mistake to believe that nothing should be done to address present day concerns and issues during a 'restoration' but when considered, it should be done to improve the course, not the handicaps and personal outlooks of the committee members involved. We are not playing in the 1920's or 50's for that matter. Mother Nature, irrigation and maintenance have for the most part changed many original designs, so unless members are prepared to elimniate irrigation and throw away much of their high-tech maintenance equipment, a 'true' restoration will not happen.
