Prior to initiating your bug out process your first thoughts The Lost Ways Review should be where are you plan to travel to. Do you have sufficient fuel to get to your intended destination? I always try to figure a tank of gasoline to get to the final bug out spot. During any sort of evacuation you will encounter bottle-necking at the gasoline stations. There will be no easy tasks for getting fuel for your vehicle.
In some cases, it may be rationed or the station may not even have any fuel to sell. Keep clearly in mind the type of vehicle you will be using as this could play a major part in where you bug out to. An 8-cylinder SUV uses considerably more gasoline than you would consume with a small 4-cylinder station wagon. As such you will need to consider what you can carry in regards to food and water. Smaller vehicles hold less than full size trucks.
If the power grid is disabled you may not be able to fully use your GPS. Over the last several years I have grown very fond of my Tom-Tom and can not even think of life without it however as a backup I always maintain a good briefcase full of old fashion, hard copy maps just in case they are needed. Don't overlook the value of a compass in your navigational efforts as well. The two items - maps and compass are unbeatable.
