The river rips em up???? You must have cracked our skull?!!! As for the lures and line......all biodegradable and overtime "goes away" but cigarette butts, they last a bit longer since they are made of "natural" ingedients (metals) where your butts are synthetic and take so very much longer to break down. I'd still fish with you but you should (in french accent) go to box.....feel shame.
