I have played a course in Collierville, Tn called Spring Creek Ranch that I believe COULD be a terrific Open course. It does have sufficient land adjacent to support an Open, like the USGA likes to have.
I would love to see more modern classics be used as future Open sites. I am growing tired of the same old courses being used each year, with a "so-called" facelift making them better.
I am one that believes that today's course quite often are superior to the great majority of courses built long ago. Not all from any era are superb, but there are many more great courses built in the 90's than in any decade, possibly ever.
