Also, learn how to fly drones if you can, if (when?) things go shit-fan-hitting globally, that seems like a really useful skill to have in your group, considering how the face of warfare looks at the moment.

With a quick reminder: If you in any way can, don't do this solo, connect with others, don't get arrogant about it, either. The fascist preppers have a huge weakness in their narcissistic individualist "I am better than the sheep" prepping style. Being able to actually support and organise a community in the potentially coming chaos is important.
