At least take water. it amazes me how many people I see on the trail (just park loops, not backpack trails) that dont even have a water bottle.Anyone who decides to walk out in unknown woods, without basic 10 items(under a cost of $75)and leaves no message with a responsible party, or clothes to sustain deserves a little anxiety of being lost.
Sat phone, cell phone, cheap 22 cal gun and 100 cartridges, might save your life.
Go light, learn stupid lessons, and hope you're found. If you are hurt, hope you had first aid class in Boy Scouts. At least put out a distress call, hang an orange or yellow shirt visible to ground or air S&R.
Most lost could be prevented with a little reading and backyard practice. Compass and map and GPS doesn't hurt either. Water. little non perishable snacks and food.
I have been turned around a couple of times and a map/compass and calm solved my dilemma.
DNR even drove up and offered me a ride, was only 3 miles turned around during deer hunting season. Got home in time for dinner. Wifey knew to call if too late, and my boot impression was on dashboard of my truck in tin foil. Good luck.
