Bunkers can be saviors or executioners, beacons or surprises, annoyances or eye candy. Nowadays, most of them are money pits, because golfers expect their hazards to be flawless.If you think you know everything about bunkers, you need to encounter more of them on more courses. They're as diverse as those who design them, shape them, rake them and curse them.
