When I head out even for a quick jaunt on the trail, I started carrying an XL sized ziplock bag in my hiking pack to do one thing: help clean up trails. Why? Because I got sick of walking past bits of trash on my favorite trails and not having a safe way to haul it out. This is a great habit to get into that I really recommend for everyone. I do the same thing in the neighborhood. I always carry a plastic shopping bag or two and pick up whatever trash I see lying around. By far the most frequently picked up item is empty water bottles. I can't understand why those just get tossed everywhere! Anyways, is there anyone else here that does this? I think it's just a great, easy way to really help clean up the land we want to enjoy.
