Welcome to the forums!
I second what Dwight said above, but for some reason the link he posted didn't work for me.
The three Georgia units that he refers to are,
Georgia Unit Top of Georgia Airstream Park
The Georgia Unit is the biggest unit in Georgia (and one of the biggest units in the WBCCI), and as Dwight said, has the Top of Georgia Airstream Park.
Southeastern Camping Unit Southeastern Camping Unit (012) | Moving WBCCI Forward!
The Southeastern Camping Unit is a quite new unit that seems to put on a lot of weekend activities to attract members who are still working.
Coastal Georgia Unit http://coastalgeorgia.wbcci.net/
As its name implies, Coastal Georgia is a small unit with activities mainly in the Southeastern Georgia - Northeastern Florida area.
There is a lot of difference between units, so you might want to look at their web sites, maybe attend one of their rallies, and see which one fits you best.
Again, welcome to the forums, and hope we can welcome you to the WBCCI!
