Cleaning up our country's rivers one old tire, barrel and bowling ball at a time

As we all collect more and more stuff, more and more of it ends up in our rivers and along our shorelines. One group - Living Lands and Waters - has spent the last 20 years cleaning it up. The list of things they've found out there is wild. Almost as long as their list of sponsors which include John Deere, Budweiser and many more. Oh, and did I mention they live on a barge? And that college kids spend their spring break with them? An amazing story of a group of adventurers out making our country a better place.
