2-22-2021 - Today, I point you to TWO free resources, both from the Church of Jesus Christ of Latter Day Saints (LDS). The Mormons have taught/required preparedness and self-reliance of their members for generations, and have accumulated much practical knowledge on the subject. You can get a free download of the LDS Preparedness Manual, by clicking the link to visit their website (you'll have to give an email address to download the most recent edition). If you don't want to give your email address, you can still get the 2011 edition at this link (link opens a .pdf).
Another useful and free resource by the LDS is Basic Physical Health with Limited Resources (link opens a .pdf). Maintaining good health before, during, and after a SHTF event is extremely important. This book gives information covering Disease Prevention, Cleanliness and Sanitation, Family Food Production, and Basic Family Medical Care, even when resources are limited because of poverty, war, or natural disasters.
