Here is some food for thought.
Could todays cameras help to save your life?
Should you have purchased a camera with the GPS function and you ever get lost in the woods or some where on the road where there you might have to send some one for help you can use the GPS to plot the coordinates for the search and rescue teams.
The GPS on the cameras unlike the GPS on the typical cell phone is software based and communicates directly to the satlight giving you your position.
If your in a real bind, you might be able to use the map in the camera to get you out.
Mind you though some GPS systems area not perfect so it might be best if you stay right where you are.
Let family and friends no the areas you are going to hike into, Ask the forest ranger to rent a radio and a locator beacon, and make sure you return the Radio back when your finished.
or if you have a portable CB take it with you. you can use the GPS on your camera to relay it to a trucker.
and if you don't have a camera I might suggest getting a GPS unit and if you already have one and it can be removed from the car, as some are known to have there own batteries take that with you.
The idea is to be prepared and be ready. Always take a map and compass with as these are fail safes and don't need power.
Remember the only person that truly can save your life is you.
What you do and prepare for will ultimately mean your survival or death.
and here is something else to think about.
if you have a camera and or cell phone and you get lost, you can use the magnifying glasses to start a fire to get you warm.
Also if your a city slicker and you think that the woods have nothing that can harm you cause your some big bad dude, just remember, there is something bigger and badder then you in the wild-lands of the wilderness, Cougar, Bear, Deer, Elk, won't care .
The best way to survive is to use your head.
Understand the area that you are going into, respect the laws of nature and if you don't know those laws, I suggest you stay with the city parks.
Accidents can happen never go hiking alone and if your in a group discuss what to do incase of an emergency if your hiking for 1 day take 5 days worth of food for Each Person in the party.Take warm clothing and dress in layers.
Most of all do your king that fits your skill level. Stay on Marked Trails." Don't become a Dead Fred."Think 5 and remain alive"
