Paul,
I was a member years ago when Lanier GC was Canongate-On-Lanier, but didn't reup when it was sold to the membership. I hate to see the course go, but this is a definite trend in Atlanta. There was a thread recently about the number of courses that are going this way, and it is a bunch in Atlanta.
I saw an ad this weekend that announced that Lanier is open for public play from now until the closing sometime next year. Also, at Alpharetta CC, where I play, we have picked up a number of new memberships from Lanier. As I understand it, we are for sale also, but will remain a golf course.
