When my grand daughter and I went the other day I cleaned up a lot of discarded line and found 15 brand new tiny tube head jigs. I make my own but they went right in my jig bag, better there then in a someone's foot. Always have a garbage bag in my tackle backpack for picking stuff up.

I also carry a gallon zip bag and we pick up the goose down feathers and bring them home to clean up they make nice collars for flies and jigs.
