I'm reminded of a quote of David Ogilvy, of the ad agency Ogilvy and Mather:

"As a private person, I have a passion for landscape, and I have never seen one improved by a billboard. Where every prospect pleases, man is at his vilest when he erects a billboard. When I retire from Madison Avenue, I am going to start a secret society of masked vigilantes who will travel around the world on silent motorcycles, chopping down posters by the dark of the moon. How many juries will convict us when we are caught in these acts of beneficent citizenship?"
