To stop being a lazy bum, here are some I can think off of the top of my head:
Suwanee, GA: My house (if you're making a map DM me on discord and i'll give you a rough area)
Bethlehem, GA: At the VFD
Walnut Grove, GA: At the town hall
Oxford, GA: Mounted next to the SD-10 on Whatcoat St.
Newborn, GA: Water tower
Homer, GA: S of downtown somewhere... Don't remember exact location
Jonesboro, GA: Fire Dept. museum in downtown
Hawkinsville, GA: Midway VFD
Three in Pike County, GA on the water towers in Williamson and Molena, and one behind the fd in Meansville
Downtown Adairsville, GA
I'll add some more if I can think of them.
