You can't get into Flyboy without an appointment. It's a private course, and from what I hear, incredible.
Perkerson is a good temporary course they set up for Sunday dubs.
Saturday morning is a big time for dubs at Alexander---tons of folks show for that.
Sunday morning, my favorite gig is Peanut dubs at Redan, which if you're going to Atlanta, you should play. It's older, versatile, and fun, and the dubs group is a lot of fun. 10 bucks gets you all in for a round, including 3 or 4 ctps. I've only left a few times without winning something.
Don't play Lenora unless you go to Friday night GLO. It's a wide open, windy, and quite frankly, boring park.
White Oak, Sequoiah are two of my favorites in town.
Good luck. I'd like to know what you did and what your favorite was.
Not sure what "Roswell in Appling GA" is, but East Roswell Park is a good wooded course.
