Same area that they film The Walking Dead.
Wanna bet that the ‘prop-dept’ for the TV show rented out the outfits and weapons?
There are a bunch of productions in GA. TWD is probably the best known...but even Family Feud is produced there.
Good morning FRiend :) Sure hope this finds you and yours well.
I am pretty sure that WD is filmed around Senoia, which is well down south westish of metro Atl. Stone Mountain is more a smidge north, but mostly due East out of Atl.
Now if you are based in Atlanta, with it growing like a mushroom fairy ring, it probably is not much different drivewise, but geographically, they are well apart :)
Take care, stay well!
