I regularly take a garbage bag and pick up garbage while out hiking. I make a game with my son: one point per piece of garbage, any size, and the most points wins. Around our house is pretty clean now, but we're always out to different areas doing the same, and there's no shortage of weird junk in the woods. We have a bag limit but don't get charged by weight so it's not a big deal to dispose of. I can't say I would do that if charged to dispose of it, though.
