Just for the heck of it, I'm going to post my photos I have of some of the old siren poles. I sure didn't see any riots or chants about it though...
Lewis Road and Litton Drive in Stone Mountain:
Stone Mountain's old railroad depot:
Old Amoco station near the intersection of Rockbridge and Hairston roads near Stone Mountain:
Dunham Park Road, Decatur (Photo taken from I-285):
Medlock Rd, Decatur. The pole is that one that''s just "Kinda there" behind the tan building in the center:
I usually don't drive around to go specifically to them. If they are in the area in which i am, I usually stop at them and snap a few photos of them.
