Everything I had seen also listed Joe Lee as the architect at Hidden Hills.
This is the second long-time Atl. club to close for development in recent months. Canterbury in Marietta, with 450 members, closed at the end of November to be developed into housing. Canterbury wasn't a great golf course, but it was a lot of fun and seemingly a very viable club. Just too much money in housing for the 8 owners to pass up, apparently. Ironically, the 8 owners were members who bought the club several years ago, ostensibly to keep it from being developed! Accounts of the clubs closing portray the membership as feeling completely betrayed, as they had almost no notice that this was coming.
(Canterbury in listed as "architect unknown" in the best listing of Georgia courses that I've seen. If anybody else knows more, I'd love to know.)
