Eric,
I couldn't agree more with you.
Flat, boring fairways are one of my pet peeves.
This makes # 14 at NGLA one of my favorite holes.
At my home club in NJ, the 13th hole has a wonderfully uneven fairway.
For 40+ years I've fought attempts to level it.
Not long ago I was playing an OLDE golf course and commented on the magnificent, undulating, uneven fairways.
I commented to my host and others that if this course was built today, the fairways would be pretty flat, depriving the hole and the course of its unique character.
While drainage has to be considered,, and water moved, there's something special about undulating fairways that produce varied lies.
