C'mon Brent, its easy to build a hard golf course. I could do it, you could do it. And I'll sell it to the owner as reducing maintenance costs by having less fairway height mowed area, plenty of wetlands and native grass to keep the environmentalists and birdwatchers happy, and of course miles of OB for all the lots we're gonna sell. And judging by some of the crappy golf courses I've played from time to time, guys like you and me who have no business designing courses apparently sometimes do!
The problem is that it is way too easy to build a hard golf course. The trick that comparatively few courses pull off is to be challenging for even the best players without being a horror for the guys who can't break 100 on a treeless muni.
