Back in the Halcyon days, prior to gca.coms first mention in a national sports magazine, (Archives unavailable as far as I know) one of the ethos was discovering where developers, architects and even people's opinions, were mis-imformed, leading to many mistakes made in the arena of golf course development and architecture.
The following link has zero to do with golf, but, has everything to do with hindsight and the honest intellectual admission of wrong doing.
Warning; The following piece is extremely long in viewing, but is equally thought provoking on many levels and subjects.
My hope is we all become better informed and eventually look within ourselves and our knowledge to see how easy it is to be wrong.
