I live over here off Peachtree Corners Circle close to occupied Norcross. Go to many restaurants near the Perimeter Mall area and anywhere else in North DeKalb County and you will see what I am talking about. Yes, I have noticed all of those Spanish signs popping up along Cobb Parkway, probably like you have. I have been eating more at home these days, considering all of the illegals that work in these restaurant facilities and the reports of TB making a comeback with all the illegals flooding our country.
Sheesh, you're close to Chambodia. Norcrea is not far behind. It's as if many Asian people do not want to assimilate either. Check out Buford Highway. In Cobb County, it's primarily Mexican illegals. The same goes for Fulton, Cherokee, and most of the rest of the metro.
I live in southern Cobb County, so our communities are slowly being flushed down the toilet. All of them with the exception of Vinings, the East-West Connector corridor, as well as parts of Powder Springs.
