Since much of this conversation has been about discarded fishing line, I'll bring up some of my major dislikes; abandoned trot lines, brush lines, and jug lines. Trolling motors hang up in them, lures are lost, casts are redirected around them; I came across a dead deer wrapped in one, and fish are left to rot. The laws state the lines must be checked regularly, but it's obvious they are not, and many have no ID tags. It is illegal to tamper with those abandoned lines, so I wont say that I ever have.
