When I was a boy, my father had a saying whenever we went camping: "Always leave things better than you found them." Whenever he quoted this pearl of wisdom we knew we were going to be cleaning up the campsite before the fun started. Cigarette butts, pop-top's, candy wrappers ... there was always a few things littered about. So we took three minutes out of our day, picked things up and dropped them in the trash. It was and is still part of our family's camping tradition. Thanks Dad.
