Surfrider is having their 3rd Annual Paddle for Clean Water this Sunday.  If you’re wondering exactly what a "Paddle Out" is:

A “Paddle Out” is a public rally where citizens concerned about the state of our coasts and ocean gather on a specific beach to make public presentations and take action. Some of those attending will paddle surfboards, kayaks, etc, into the nearby water to form a “circle of solidarity” in a showing of commitment to turn around the trend of degradation. The event is not only for those willing and able to paddle – it is open to everyone who shares our concerns for the coast and ocean.

It’s basically a media event, to garner attention and support for a worthy cause.  The focus of this year’s paddle out is to highlight the findings of Surfrider’s annual State of the Beach Report.  Presumably, even if you can’t make it to the official rally, you can do your part by spreading the word where ever you decide to paddle out.
