This is the most sustained ugly I have seen. Yes the RFK murder was bad, but it was not within a campaign with so much vitrol. Yes are still suffering from Carter, I don't want to think about an Obama adminisration.

Hmm.

Poison ivy, maybe? Dry acid?

Yes, I'm a vengeful kind of person. I shouldn't be, but I am. You mess with my stuff, and the term 'disproportionate response' comes to mind.

Go low-tech: red pepper powder in copious amounts. If they don't know they've got it on their hands, they'll go ahead and scratch their eyes/pick their noses.

The next level might be rat poison.

Use laundry bluing--the stuff cleaners use by the thimbleful and spies use by the cupful--the poor man's dye pack. Cuts down on people poking around your trash, too, for identity theft. Put some inside a cheap ziplock bag and glue the bag to the back of the sign--another one attached to the post.

You can make a transparent mercaptan(the 'rotten egg' smell added to natural gas) grease that would take weeks to clean completely. Get the base at odor-tech.

Are you kiddin' me? Do you know why Ronald Reagan economic policies got the name "Reaganomics"? It wasn't because it was so good, that I can tell you. Ronald Raygun was awful for the American people and the economy. He blew tax payers billions after billions on crazy half baked ideas and schemes and government contracts on force fields, Death Stars, and any other wacko ideas that were pushed his way. You name it he blew American tax dollars on it. Who would've thought that 20 years later all that crap would come full circle with the son of his Vice President. I for one can't wait for him to had the White House keys over to Barack Obama to get this country back in the right direction and back to the peace and economic bliss that we enjoyed in the Clinton years.

This led to a discussion between A the H and me about what the best substance would be to coat the back of the sign with.

Actually, you should bolt the sign onto a post with exploding stem bolts. That'll put a stop to those shennanigans straight away.
