Just buy the things on my mini bug out list and follow my advice on choosing a location. Bring a gun as well for dangers along the way. Timing is most important because with just your bag you can survive 3 days. Hopefully you can reach a safe location and assimilate into a trustworthy group there. Part of the reason why I’m warning ppl here is so there will be more preppers. For each prepper there is one extra ally and one less enemy. The chances of forming a community increase.
