My wife and I take near daily walks through our neighborhood. One day we decided on a whim to take a couple bags with us and pick up trash as we walked. Ended up turning into an impromptu competition and we were laughing our asses off by the time we finished the 1.5 mile loop and got back to your house. We dumped about four bag loads of litter in our garbage can, and now we do it once every few times we walk. We couldn’t believe how nice it was just to walk around and not see litter for once! Just an idea :)
