Yeah it was just a clip within a program about the Appalachian Trail in 2009, hence the reason it ended suddenly.
Figured it was a good way to show the Smokies fisherman how acid rain is much worse to our fisheries than too many fisherman, or dare I say it OTTERS
Also pretty cool to see people you know working the streams, gathering the evidence to try to make sense of this complex problem, and hopefully will ultimately help us clean up the air and water more before it kills out our fisheries for future generations to be able to enjoy as much as we do.
