I am going to state generally the bug out plan that I have set up.
One safe spot is with in walking distance. It would be a hike but it can be reached on foot. The another is under a quarter of a tank to drive to get there. Another is slightly over your average tank of gas to reach and still another is over two tanks of gas away. These are not the only ones I have but they serve as examples.
Our place also serves as a safe spot for others. If something hits their area and doesn't hit ours then we will be taking people in. I have supplies and items ready to do that.
Don't just have one plan. You need to have a number of plans depending on what happens. You can't prepare for everything. But you can try. And the act of planing leaves you in better shape to deal with the strange quirks that live just loves to throw at you.
Good advice. What you're planning for may not happen the way you've planned. More and/or flexible plans will be better.
From what I have experienced going through a planned and slow bug-out to a safer location, the prep planning I did before hand, came in very handy. Even in a planned bug-out relocation, there are numerous unforeseen difficulties. And yes, mobility will be crucial. Kinda funny that many of the items I was glad to be packing into the truck, were the prep items.
