Is there a valid reason why some bunkers have liners and some don't? I understand their "use" to prevent rocks from coming to the surface, but can they help drainage? Does it make any sense to have liners in shallow flood prone bunkers?
I have played too many courses with the liners showing, it seems when they are repaired the liners are history. Sorry if this is a dumb question from an old Pro, but a question from a 27 handicapper got me thinking about it.
