To prepare? I have a couple of months cash, food/water and gold, first aid,etc… All stashed. Always have the tank full on the 4X as well as 3 extra cans. Just visualize what you’d need for a few weeks in the outback.
Never hurts to be prepared and it’s peace of mind. This is just good advice for any emergency, anyway.
Keep it to yourself. It’s your business and no one elses.
