I lived offgrid for 3 years using my survival instincts and skills. I brought sustainment for 3 months, and that was more than enough to get to self sustainment. I built shelter, survived winter, make clothes, made tools etc. I had a few cheats and hacks along the way (solar panels, batteries, wind turbine, well drilled on property). But I stayed detached from human civilization the entire time. Honestly in the Pacific Northwest USA, food is the least of your worries 😂
