New York City has placed sewer-sized decals on sidewalks outside subway exits to assist passengers in finding their final destinations. You all know the moment. You come out of the subway -- even in the city you've lived in for years -- and wonder, "Which way is West?" You're angry at yourself when you walk a block in the wrong direction. As you turn around you fret, "Did anybody notice?" My only concern is that by placing the signage on the ground, not enough people will notice it, or that it will be obscured by passing feet. --Dana Goldstein
