Tom,
I agree with you.
Ally,
How would you define a "hazard"? Forrest and I define them in our book on hazards as both "Formal and Informal" but either way they are hazards. A old rock wall, broken ground, a tree, a road, a mound, a sandy waste area,.., in an interview for our book, Tom Doak called "short grass" one of the best "hazards" if used properly. I very much agree with him.
When the game of golf was first played, a hazard was not an actual thing or object. It was a concept, a situation a player got himself into. A problem not avoided caused your ball to be in trouble and the outcome was not known until you preformed. Only as time progressed did such perilous situations become known as "hazards".
Donald Ross might have said it best about great holes and great courses:
"The ideal course is one that presents a test of golf for the everyday player and the first-class player. A properly designed course can take care of every class player. My aim is to bring out of the player the best golf that is in him. It will be difficult to negotiate some holes, but that is what golf is for. It is a mental test and and eye test. The hazards and bunkers are placed so as to force a player to use judgment and to exercise mental control in making the correct shot."
We should all forget how the USGA defines hazards - the point is every great course/hole has cool or unique or memorable (hazards) and that is what makes it great. If there is nothing "hazardous" about a hole then there are no problems to solve. How can it be great?
