To the officials of the PGA Tour, you blew it! BIG TIME! On the 18th hole in today's final round tournament leader Dustin Johnson hit it into the gallery. He was not thinking it was in a bunker, it was where the gallery stands.
But in your antiquated thinking, you had it as a bunker. Granted when the public plays the course, it is a bunker, but in your course set up you took it out of play to make the final hole a little tougher for the pros.
If you want it to play as a bunker, put it play. But if you allow the gallery to trample it, you lose the definition of the edges of the bunker and it plays a lot differently. Dustin Johnson should not have been penalized for your incompetence.
A course is designed to be played a specific way, don't mess with it and the game will still be ok.
