Take heart, gentle traveler, for there is a way to mindfully take joy in the true national treasures of the United States. The men and women protecting our parks are fighting an uphill battle to protect us from ourselves, and we can help them. Follow the rules posted on the clearly posted signs. They are meant to protect both you and the wildlife. Place trash in proper receptacles. They’re everywhere. Adhere to the trails. The maps are free and comprehensive. Do not try to steal the limited, federally-protected nature. Basically, don’t be terrible.
