Hi Anne Marie - it is through grassroots startup programs like yours that most of the work gets done.  Get in contact with Cook Inletkeeper at inletkeeper.org or 1-888-MYINLET for tips on how to get started in your area; I think 1-2 coordinators per beach and their volunteer groups and bags/supplies are the recipe.  I don't know how the haul-out to waste sites works though.  The coordination with volunteer vehicles and waste management might be the tricky part.   Start in one place first to see how hard it is and to get your basic education on how to do it.  Best of luck! I think you're an inspiration!
