An I wrong, or was the first question mostly about building good courses on flat, non descript land, more than using templates, or whatever?
There have sure been many (too many, at least in my portfolio) built on flat land. My theory on why no more great ones?
This was the first 18 hole course in America. Maybe they didn't know better than to pick a property with some roll? Since then, I think most clubs aspiring to greatness have at least tried to find better property, since most of the GA guys wrote that it took good property to make a great course, albeit, not hard to build a good one on average property. The trend to great property may have abated for a while, but has been back in force for the last 20 years, no?
Not to mention, there aren't too many places quite as flat as Chicago! Florida, but all those courses were built to support residential first. Some are ranked quite high, like Indian Creek, no?
