I have never been to the Highlands, but from what I have seen it appears more severe than the Palouse...
I think we spend way too much time comparing locations with Scotland. Bandon "looks just like Scotland" Sandhills, "looks just like a Scotish links course"....on and on...
Bandon looks like Bandon, Oregon to me. Sandhills looks like many places I have seen here in the west, only the soils are better suited for golf.
Sorry for rambling...I just got in from playing 36 holes, with two rain delays, and some howling winds, on a "scotish links style" course....maybe someday I'll actually play a scotish links course.
