The head gruppenführer of my HOA had tried (amongst other things) to tell my I could not park my RV at my home. I less-than-politely informed him of things he could do with sand and his posterior. There's no rules prohibiting a lot of the stuff that sets him off, but that doesn't stop him from telling people that they can't do this or that. He once told me that my big, inflatable Homer Simpson Santa Claus was too "tacky" for the neighborhood and that "all the other homeowners agreed" with him that it has to come down.
He dont even wave at me anymore after the response to that one.
