... to ask before you place a political sign in someone's yard?
A friend of mine is the campaign chair for a candidate for city council, and he just drove up in front of my house, got out of his car, and placed a sign in my yard. Without asking.
Granted, I know the candidate - I voted for him last time around and have every intention of voting for him this year. But having the sign placed in my yard without so much as a 'how do you do' just fries my ass.
