They can't have spent much. They only have a few sirens:
St Anthonys Drive and Midland Avenue intersection

Lee Street at Easter Seals organization
https://maps.google.com/maps?q=winder+g ... 5,,2,-7.86
Highway 82 at the Barrow County Administration office complex

Winder Fire Department

The Model 2 was supposedly moved from the fire department and placed in Fort Yargo, then there's the elusive vehicle siren in a box at the city pond. All in all, they have pretty decent coverage. Barrow County is not fully covered but most cities at least have 1 or 2 sirens. Auburn/Carl has at least 3 Whelens that I know of, Statham has a Model 2 and a Vortex, Bethlehem has a Model 2 and Dacula has a Vortex.
