I am only 2km in. I so understand your situation. (But a fraction of your distance) i think it is amazing that you are being prepared! Gathering your own medicines and food. When I forage, I always dehydrate what I can, to add to my cooking for the winter. I am so glad you made it out. I have 3 staples...colloidal silver, oil of oregano, garlic. I use homeopathy. It's shelf stable, and small to carry in a bundle. I applaud you for what you are doing!!
