I saw a series of these posters on my walk home yesterday and although I know it's obviously some guerella marketing effort to promote the new film Zodiac, I'm tempted to call 311, or as Rachel does, go straight on to 911.
I find it a little disturbing that someone thought this was a good idea to poster up major cities with the very same markings left by notorious serial killer whose identity remains unknown.
At least the signs don't smell like gas, or worse yet, maple syrup. Then I would be really scared.
