If you can carry your container into the place WHY CAN'T YOU CARRY IT OUT!!! Same goes for non-returnable bottles, zip lock bags, the packaging your favorite lure came in, and even the spools that fishing line comes on. For that matter, pack out your discarded fishing line instead of throwing it in the water only to end up wrapped around my motor prop. Maybe we should tax -oh excuse me- put a deposit on these things to make it worth while to carry it out.
