Ricardo, actually I'd be keen to hear what someone near the scene such as yourself thinks are the best courses in either Argentina or Uruguay, and any/all other countries in South America plus any unknown out of the usual golfing focus unusual courses as well.
Tom, bit of both really as there is a tendency to focus on the same areas and yet out there in the overall golfing world there are probably to be found the equivalent of Mulranny's and Durness's and Rosehearty's and Himalayan Clubs being played by local residents probably without the most modern equipment but still having fun...and maybe with a few magical holes yet to be internationally discovered as well. I recall a recentish thread on a 9-holer in Chile where one par-3 was completely under the canopy of low trees played to a tiny green and I think you posted a photo of an interesting hole in Southern Argentina recently. Thus looking forward to learning more as your new Confidential Guide series progresses. A splendid venture (and adventure no doubt).
