Scavenge Challenge August 2012 - 4. The theme is protecting wildlife. Show an example of wildlife conservation in your area.
Each and every drain has this painted on top, to remind folks that the storm drains (eventually) lead to the bay and nasty things like motor oil and anti-freeze should go elsewhere.
I can't quite tell if the blue blob on the right is a Dolphin (which I've seen clearly painted in neighboring communities) or a happy shark.
As people actually go out into the bay, I'm thinking the PR folks would probably prefer I view it as a Dolphin.
