Mike,
I, like Grant, haven't played I.G.C (Otatara) but have visited. Parts of the site have great 'crumpled' ground- perfect for golf. Trees have adversely impacted the golf however, as have some drainage issues. There is no doubt, it is a course worthy of mention- and that it is so close to Southland Golf Club (Oreti Sands) makes them a great 'double header' for those making a visit to this most-southernly part of NZ.
Steve,
Speaking of the "The World's fastest Indian", a movie I enjoyed too, there is a pub in between the two golf courses mentioned above called 'The Cabbage Tree' which is very good, and has many photos from the movie shoot on the walls.
Invercargill is an interesting place.
