This is kind of a side bar to the plastic bag thread. Like everyone else here I'm a huge fan of reusable grocery bags. On the occasion that I don't have one with me and stop by the store for a few things I request plastic because I use them to clean up when I'm walking my dog. I'd rather not use them at all, but don't have a good alternative. I've thought about using a heavier, reusuable plastic or rubber bag. Poop could be tossed on the compost pile without any real worries. The bags could easily be flipped inside out and washed with a hose in the warm seasons, but would be a royal pain in the winter. Does anyone have any solutions/practices that don't take 500 years to get rid of?
