Hey Andy,
Last night I was at the Red Brick Station in White Marsh, Baltimore, MD and saw the Declaration of Beer Independence poster hanging above the urinal. I really didn't look to see if it was in other locations in the joint and didn't think popping out the camera phone at a urinal in the men's room would go over very well, so you'll have to take my word for it. But yeah the stuff is out there.
Cheers!
