That was basically my next thought. But pass by your local government first. At the absolute very least, it's more effective when the 'big bad government' doesn't do something to keep its citizens safe, when it makes the news.

Also see which level of government maintains or patrols which local roads (I know, this gets cumbersome). You may also need to do something similar at the county level. At the very least, it would then make finding people a bit easier.
