While I do not plan to bug out, you have to be open-minded to the possibility. For instance, there is a railroad only about a quarter mile from my house. This is close enough to force us to leave in a hurry if an accident occurred in the wrong place.
Now there are a couple of ways to leave either on foot or by vehicle. We have the normal 72-hour packs made up and ready to go, but what about if you had a few minutes and the opportunity to leave by vehicle. Do you have any idea what you would take? We have sorted our preps into sort of a modular system. We have put the critical items into boxes that we would load in order of importance. Loaded into the right boxes into one SUV we could easily live outdoors regardless of the weather for a minimum of a month. Attached to the boxes are lists of medications or other important items we would need to grab.
Because we would have the basics using skills that we have learned, we could extend that month into a much longer period. As I say while our plan is to bug in, things can always change. All your plans should be flexible and simple. In an emergency, the simplest plan is often the best. Do a dry run of your plan and make sure it works. It would be embarrassing to find out the boxes won’t fit in your car in the middle of a bug out.
