Is anyone aware of or has anyone done any message testing related to storm drain stencils? I know the general rule is to tell people what we want them to do rather than what we don't want them to do. Hence 'Keep Our Waters Clean' vs. 'Don't dump', but has anyone tested various messages for storm drains? I am wondering how "Only Rain Down the Drain" will play? I wonder if people will make the connection? Plus thinking about the research I have read over the years that "clean water" plays well - if "Keep Water Clean, Drains to Stream" would be more effective or less effective?

Thanks for any help.
