Denis Griffiths has some noteworthy bunker placement on his new course south of Atlanta, Crystal Lake. He was quoted in an article as saying he was influenced by the time he spent in Scotland building St. Andrews Bay.
Many of his bunkers encroach on the fairway, which introduces risk/reward. Are we seeing more of that? I would hope so.
Bunkers on the par-5's challenge all 3 shots.
Sometimes bunkers indicate the line of play; in other cases the bunkering induces visual deception.
There is a par-4, #13, that has more sand in the fairway than grass. There are at least 3 options off the tee, stretching from one side of the fairway to the other. It's almost over the top, but very intriguing and very fun.
Throughout the course bunkers are used to encourage and reward aggressive play. I'd like to see more of that.
