Lon, et.al.

I think I might have posted this in the recent past, but it is worth a revisit.

Our municipality has a reverse 911 system called CodeRED . The system alerts for the specific area the municipality has contracted with the provider to warn about. I have all of our cell phones set to receive the warnings, and it has a specific ring tone/vibrate pattern. The way ours is set up, it starts warning one county away from our town.

Check with your local governments to see if something like this is available for your area.
