A friend of mine just turned me on to this blog. These guys are sailing to Hawaii on a raft made of plastic bottles to bring awareness to the gross plastic pollution in the Pacific Ocean. The site states that they are:
SAILING TO HAWAII ON 15,000 PLASTIC BOTTLES AND A CESSNA 310, TO RAISE AWARENESS ABOUT PLASTIC FOULING OUR OCEANS.
Those guys are out there right now. Looks as though they are having a hard time getting out into the Pacific due to the currents and winds. Seems they are getting pulled down towards Panama. Give their blog a look over and a shout out.
