Documenting your itinerary and route on a map may could save your life. Sharing your agenda with a friend -- and setting a time (or times, in the case of a long trip) to check in -- will reduce the chance that you could experience the nightmare of being stranded with no one aware of where you are and no efficient way for people to look for you [source: Hiking Dude].
Clearly mark the route you will be travelling and all the stops you plan to make along the way. Schedule check-in calls with family or friends at regular intervals. Give one trip itinerary and route map to your check-in contact and bring another copy of your plan along with you to file with local park rangers or authorities before you set out -- many parks have Web sites with the appropriate contact information. It's also a good idea to leave a copy behind in plain sight on the dashboard of your parked vehicle. And for the tech-savvy camper, some monitoring services maintain Web sites where solo campers can file trip itineraries -- or you could carry a GPS-equipped device that will allow you to communicate your status from deep in the wilderness [source: Owings].
