Every time I have put up signs in my neighborhood, they have been vandalized or stolen. Rotten libs!
Have you thought of putting the yardsign in your window?
There are unfriendly areas where all yard signs will be removed overnight. The only way to beat them at this game is to put the signs where they can't get to them.
You need to mix up a little batch of touch powder for your signs.
Ammonium nitrate with iodine crystals. Used it in college on a squealer’s room who never did it again.
