Hey, check out Alan’s article in the latest issue of American Survival Guide. I just got it in my mail, though it is dated “December 2016.” Alan wrote about SODIS, solar disinfection of water using plastic bottles, a viable option where fire is not practical. I suggest you get a copy and check it out. It’s on page 22.
Also, you might enjoy the article by one of my early martial arts teachers, Barton Boehm, with whom I studied Seiken. Barton wrote about the use of sticks “A Survival Stick Can Be Your Best Friend,” on page 36. You will enjoy this Jason!
