JC,
I guess it is a fair question, as long as you aren't implying that it is all about who are the favored architects.
As for the Mosaic site, it was indeed all very flat to start, but the scale of the earthmoving they did here was off the charts ... I would guess it is on the order of 15,000,000 or 20,000,000 cubic yards. The main lake near the clubhouse is 400 yards long by 40 feet deep, with a 100 foot tall dune along one side and 30 to 50 foot elevations on the golf side. So the scale is just not like anything Pete Dye could build in his dreams. There are also a lot of smaller, random, man made features that are pretty cool in their own right. Put it all together, and it is really no different than what God used to build on an everyday basis.
However, to Jeff M's last post, I would like to clarify that everything on site is sand and there is nothing we HAVE to leave untouched for environmental reasons. It is just common sense not to disturb some of the features we have been given.
