Steve,
The wonderful thing about NGLA is that if presents a challenge/quandary to every level of golfer, yet, at the end of the round, most view the previous 18 hole experience as having been a lot of fun. And that I think is due to the genius of the architecture for every level of play.
If it were within my power, I would grant every serious GCA'er two round's at NGLA, and Tom MacWood four.
Tom MacWood,
What quandry does the "duffer" face on the 1st and 18th tees at TOC ?
