Prepare For Survival In Case Of Emergencies
With today’s technology in mind, several things should always be in your emergency backpacks: A very loud whistle, and a laser pointer (in case you have been isolated in the wild, and away from accessible routes. They both can help in being located when lost. Of course today cell phones can be very helpful. There are very inexpensive battery, dynamo, and solar powered, operated portable radios. Always have your little waterproofed medicine, protein bar and matches.
