My personal siren map

[gman 1]

Here is a map of sirens I have recorded, or plan to record. The thunderbolts are just there, I have recorded none of them.
The red standing points are places I have already been; the green ones are where I have yet to stand at when/if I record them.
The blue pins are sirens I can't record but I want to.
