When we arrived in Yosemite Valley, the park ranger drilled in the leave-no-trace concept into us before issuing wilderness permits. Having these permits, allowed us to backpack in the back country. What a wonderful treat that was.
Being that these areas are ones where there is no garbage pick up, or that sort, it is imperative that we not leave any traces of our presence in the backcountry. Although it was a new way of thinking, I was able to make the required adjustments — with a few reminders here and there.
