Don't cut live branches or trees. You might need to cross someone's property to reach a campsite or activity area. Obtain permission to do so, and remember that a landowner's income might depend on his or her crops and livestock. Don't climb fences that might break under your weight. Always leave gates exactly as you found them.
Open gates can result in extensive loss to the owner.
Don't tease or chase livestock. Take special care not to startle flocks of poultry. Be conscious of any actions that will disturb or inconvenience the owner. Keep noise to a minimum, especially late at night. Pick up trash, even that left by previous visitors.
