I don't recall exactly how they defined "golf retreat" but I believe it just meant any course/club that also had on-site lodging.
And if that's true about Spring Creek Ranch, whoa... that is obviously some seriously poor fact-checking.
But I'd guess this is for entertainment purposes only... I doubt GD prepared for this to be audited.
Not sure also how they arrived at the rankings... I do know however that they did ask us rank and file course rating panelists for our input. I have to believe it's just thanks to me that Sand Hills snuck into the top 10 for Wines & Spirits. When I asked for Springbank and they had the 10, 12 and 21 year old right there on hand, well... that's all it took for me.
