Clubs and equipment ~R20k, Membership ~R10k p/a, Green fees ~R250 per round, Balls ~R45 ea.traveling (R? ). Decide for yourself how expensive it is. Not nearly close to owning a motorbike in my experience.
Worth it? Hell, yeah!!!. A very difficult target game and many people are hooked once they try it and hit one or more decent (ish) shots. Boring? Hell, NO! It is a consuming game requiring concentration, planning, finesse and athleticism combined with skill.
Someone who never tried it will not appreciate the difficulty and thereby the artistry of the pros.
