I have a pocket in my pack I use until it is full. Quite a few years ago I came upon a camp of sorts with a pile of magazines left behind. All of them were addressed to the same person so I boxed them up and mailed them back. Cost me a couple of dollars but I figured it might make a point.
Around town here there is a huge amount of construction and alot of the stuff from the construction sites blows over to Don Sparrow Lake where I clean up the shoreline in the Spring or any time I happen to be over there, though this year I think I have only been there twice.
Sad thing is I am finding more and more tapered leader packages.
One other thing, for folks who stuff there bits of leader etc. in their pockets, it is a pain isn't it? So cut a square of thin cardboard and snip a little slit in one corner and wrap your trimmed ends or found line on the card and stick the end in the slit to hold it in place. It is easier to keep in your pocket and you just toss out the whole thing when you get to a trash can....Kerry
