We all know the most remote road signs are the most popular gun targets for bored passerbyers with guns, so use that!
Make a billboard sign that is meant to be shot! Make it a picture of objects, with target circles, and challenge them drive-by rifle- wielders. If they hit the bullseye, an electronic sign (behind some bullet-proof glass) displays a promotional code that they can use online to get free soda or discount on bullets and things.-- twitch, Apr 27 2007 A hillbilly board you say?-- Cuit_au_Four, Apr 28 2007 see also: "Raising and lowering billboard" for moving target fun-- marklar, Apr 28 2007 random, halfbakery
