JMorgan, I tend to agree that there isn't much new under the sun besides sales and marketing. In the begining, with the old dead guys, golf was new, and everyhole they created in an region that previously didn't have any golf was a new and surprising break-out idea. Even if the typical list of 'old dead guys' were copying forms and patterns and templates they had seen on the old sod, or back east, they could still take those ideas to regions that didn't have golf, and be considered new and fresh and inovative, etc.
Now, if you take the collective 1500 or so on GCA.com, they have been everywhere and seen everything. If they haven't personally seen it, they have the ubiquitous media in all its forms of print-photo, internet, film-video, and the descriptive narrative in print to inform them of almost all possibilities and efforts made in the golf design field. So, it is a tall order to come up with anything new, except the sales and marketing. And even the marketting and sales verbage is nothing new, and actually trite.
I don't think it comes down to finding a new kind of land. Sure no two pieces of land are exactly alike. But, the way the holes are designed and routed across the land is generally all been done in one fashion or another, and architects have staked out some distinctive styles.
But whose style is actually new, in comparison of all the old dead guys, and all the moderns? Unless someone builds an artificial turf course.... oh wait they even did that...
