I have not been to Machrihanish Dunes yet (except before it was a golf course.) I will certainly get there this year.
I think these video links have been posted before, but they are well worth bumping up.
One has Ronan Rafferty playing and putting, the other has Old Tom Morris
and David Kidd talking about the land and the course.
Each has great video, especially on a large screen in hd.
