Depends what emergancy. We could not move live stock in less than 2 hours.
If it was never coming back would be same as back in 24 hours. Have back up id’s solids banks accounts travel arragements. Could take only immediate family. Have long term care arranged for elders if it was out of country , or prolonged no return. I have decided that Simon black way of prepping makes sense as I have had to leave a country at minimal notice before.
Everyone has a bug out bag every vehicle is stocked with a 1 month ration kit and survival gear. Only equipmet is sometimes left not fueled to go. All have commuincation devices and memorized pertinent info.
We have family in the local 5 hour area, and in several other countries.
I would have to say only way I could see this happening would be an act of God like asteroid strike or super volcano. Earthquake,tsunami,enviromental have all been considered even post shft mass of humanity migration. Our problem is we are remote if you don’t have people with proper skills it would be dangerous to be here with just a few people.
