When Story County and Ames jumped to SARA some months ago, I checked every so often to see if I heard traffic on the old system when there was traffic on the new. Nothing. I suppose there are still some other users active, like Ankeny Schools.
Story County 911 board met last week, but haven't posted meeting minutes online yet. According to prior meeting minutes, the "permanent" Racom build-out is not done yet, but getting close.
