Since joining my town's Zoning Board of Adjustment I've heard a few complaints from people about various zoning rules, but I have to say that none of those people have ever taken to calling our town leaders names on their business' signs.  In Polk City, Iowa one businessman has taken his frustration out with town leaders by using the sign in front of his business to call them names.  If you click through to the article you'll see two pictures of his sign.  On one he wrote "Our Mayor and Council Sure Are Ass—-" and on the other he wrote "Our Mayor Sure is a Lieing Little Nazi Turd."  That's what I call freedom of expression, bad spelling and all.
