I think there are also 9-hole courses on campus at Life U. and Southern Poly, but I hear they're not worth the trip unless you live on campus. I myself live in East Cobb, in a Marietta zip code. I'm half an hour's drive from Oregon Park, Wills Park, ERP, and Sequoyah. You'll find me most often at Oregon Park, but that's mostly because I know more people there. Definitely avoid Wills on the weekend, but otherwise it would be hard to go very far wrong. If you live in West Cobb, definitely take the trip out to White Oak, and if you live in South Cobb, you may find yourself fairly close to Deerlick. Otherwise Central, East Roswell, and Redan are all worth playing at least once. There's also a temporary course that's set up pretty regularly in Perkerson Park in downtown Atlanta. Check out their board on this site to find out if they're likely to set it up when you could play.
And as for dgcoursereview.com, you found a winner. They get just about everything right on that site. Timg is everybody's hero.
