Superhero Crossing: Make Way for Capes
Draken413o of deviantART brings us this (doctored) photograph of a street sign:
"Batman and Robin to the rescue zone. No parking between 7am to 7pm unless authorised Batmobile."
Hey, if you've got to put signs up for slow children, it's gotta be a million times more important to warn people about superhero crossing. Hitting The Flash will total your car for sure.
