Unless your going into country with large populations of dangerous animals your greatest danger in the wilderness is personal injury. If you become unable to get back to your vehicle then your spending the night outside. That alone can be deadly. You should make up a small survival kit to take with you, and practice the use of the items in it. Also a personal location beacon would a good bit of insurance. Stay aware of your surroundings tell someone where your going and when you will be back.
I wouldn't worry about a psycho lurking in the woods. But if your going into places with good populations of dangerous animal or a place frequented by druggies or squatters then a easily accessible side arm and blade would make fore good hiking companions along with the survival kit.
Have fun, be safe and ketch fish!
