Never hike the back country alone. If you insist, tell two people who are not going with you, where you are going and when you will be back.
Make sure you tell your trusted contacts your planned route, where your vehicle is parked, and the license plate and make and model of your car. Be aware of your surroundings. Try to see and avoid wild animals, before they see you. If you encounter any human by themselves, be cautious, trust no one.
