you do have some duck hunting opportunitys near you if you look at the ga dnr website and find the redlands wma is it public and only 30min drive from downtown athens. it does get alot o pressure but there are woodies some mallards even some geese. also there are a few lakes that are with in an hour drive of you that get a decent amount of birds each year (mostly divers). but i would start by scouting and locating birds first. find out what birds are there if you can and use a few decoys to get their attention. hunt that spot you found the day after you find it and make sure you get there early because most likely someone else has found them as well. you dont need a call to shoot birds just find the location of where they want set up right were you saw them and hunt. if you find a few spots i would hunt the one that is the farthest out of the way because there is a better chance of getting there and not have someone sit on top of you.
here are some maps of some wmas near you as wellhttp://www.georgiawildlife.org/maps/hunting/region3
also if you find someone that will let you hunt with them it helps if you find the spot with them or even on your own and invite them to hunt with you. alot of people that duck hunt in GA dont want to give up thier spots because the good spots are hard to find and they dont want someone taking thier spots. i know public land is open to everyone but still you find that good spot and you dont want anyone to beat you or over pressure that spot so they try and keep them as secret as possible.
