When I first saw the original photo from Frank Pont's website, I thought, "now that is a hazard not to reckon with. Not worth flirting with that one." And Woking being a Paton/Low redesign, with much documentation on theory of hazards by Low, I'm thinking this could be used elsewhere to great effect in extreme moderation. I don't know if Paton or Low planted the heather there, probably not, as sand bunkers were real hazards to players back then. I wouldn't want to see this everywhere but when good players start aiming to get into bunkers, then I think another hazardous medium can be effective. I wouldn't like to see it become prevalent lining fairways, but perhaps strategically spotted at those short par 4's that the pros bomb away on. Or next to a bunker or kickboard at your home club.
Any examples where this might work?
Danial, nice photo and I can understand the sentiment when the heather gets out of control. Looks great until your golf ball finds it.
