Richard Zokol's new Sagebrush course near Quilchena, B.C. is definitely "stand alone", albeit not really public. It will be open in May. From the website,
www.sagebrushgolf.com and based on pics posted on this forum, it should be very successful.
Another course in NW Washington that could be considered a "stand alone" is Shuksan, which is north west of Bellingham Wa. Not long, some big elevation changes but a heck of a lot of "fun". Nothing anywhere near it.
Then there is Sean Leary's favourite, Furry Creek, although it has some housing. Problem is not a lot of people came, except some tourists who were told how spectacular the views were on this Robert Muir Graves course. Views are spectacular but the golf is definitely not.
George Freeman has it bang on, however. re Bandon being the ultimate "build it and they will come". The other, although not advertised at all and private, is Ballyneal. As a "one off" destination, it is super special.
