Mark,
Here's some golf you may not have heard of but will be worth playing on your way down...Near Kennesaw Mountain is a course I did called
www.cityclubmarietta.com which is public and short but fun. There is another good golf course nearby reworked by Bill Bergin called Pine Tree which is a very good golf course. I don't what kind of food you are looking for but try Antico littleitalia.com/ really good bang for the buck for good food. It is located on Hemphill at the back of GT campus. And of course for the best in ATL try
www.bonesrestaurant.com.
More golf in area try http://www.heritagegolflinks.com/ or wolfcreekgc.com/
As you go towards Macon try either cuscowilla or Idlehour in Macon...let me know if you need a contact at Idlehour...In the area marked "Griswoldville" on your map around 11/22 ther is a course I did in Hawkinsville which is worth playing www.southernhillsgolf.com The owners do a very good job and it is a model for a small town golf club. Several good restaurants in Hawkinsville... from there the move towards Dublin and try the Dublin CC, just an old small town country club...there is a meat and three in old town Dublin "meat and three"which is very good and the Madison Fish Market also.
From there go to Forest Heights Golf Club www.forestheightscc.com in Statesboro. Plenty of restaurants and is home to Ga Southern University.
Not much from Statesboro to Savannah. Savannah has plent yof good golf and food. Several Carey Hilliards seafood locations are all good and you cna move up from there. Public golf wise we did one called Henderson www.hendersongolfclub.com but there is an old DR www.thewilmingtonislandclub.com and a few others close by....as TD says Richmond Hill is right down the road...try Love's seafood on hwy 17 at the Ogeechee river crossiing.
Sorry if I named a bunch of my course but I just know those better than some of the others you can access...stay warm...it's going to be cold next week...
