If you're going to put up a sign...
...do what this outstanding young lad did:
I had a commute that took me through the kind of community that has a very low speed limit in the middle and derives a large portion of its municipal revenue using radar guns. One beautiful morning there was a young teen with a hand-painted sign "DANGER! ROOKIE COP WITH RADAR 1/2 MILE".
Eventually he put out a tip jar. I paid handsomely, one must reward good enterprise and all that.
Biting the hand that feeds IT
