OK so to date I have personally found 69 of Chicago's 112 warning sirens. 12 mods and the rest 2001's. The main areas Im missing are the not so nice parts of the city. I will eventually get those, probably over the winter. I also dont have as much free time as I used to. But if anyone has anything to add to this, feel free.
