Shel is correct. Joe is Frank's son, and actually played a role in designing (and perhaps running?) the course the family built (but has since sold) in Georgia. Joe is a fairly regular contributor on Shackelford's site. . .
As for the question, if you became an adult as a golfer at Dubs, it will always be first and foremost in your heart of hearts. Also, at the August 7 Weekly Challenge event at Ravisloe the conditions of the course, and particularly the greens, was pathetic. Worse than anything the big kids faced out at Cog. Also, their attitude toward the paying customers leaves a little to be desired (ask Bill Seitz to tell you about his having hit a large bucket and then walking over to use the chipping green, only to be kicked out because he wasn't using their range balls!). It's not for me to tell other people how to spend their money, but Frank's certainly received plenty of mine over the years.
