Link?Most studied observers have declared the "Bug out" principle useless unless it is done well before the crisis.
And that is why I have topo maps, GPS fully programmed with way points in order I have chosen in preference. A compass and a normal street map.You will be turned away by armed military force at the bridge, just like in Katrina
If you think you can seal off a mid sized American city completely you are very mistaken. Will they seal the main points depending on the situation yes they may. Will they be able to seal every goat path backwoods shortcut and watch every inch of river? Not in a million years. If you know the area you can find out where the holes are. And how you can move through them.
Who said anything about stealing from farmers? I will have food in my pack when and if I have to stop to eat. Given my preference no one would even know I was there at all. I am not going to be trapped in a Katrina type situation. If you are not threatening someone a guardsman is very unlikely to shoot you. So the worst thing that is going to happen is you get turned around. No correction the worst thing that could happen is that you get detained and placed in a shelter. But I don’t think that they are going to spend a lot of time or energy trying to chase someone that is not threatening anyone down. The only real advantages they have is mobility. And in the case of helicopters and UAVs elevation. So stay small don’t threaten people and your odds are very good indeed of being able to get home or to your bug out point. No one is likely to bother someone that is in travel mode unless they are criminals. (Badge or not, not withstanding)and the friendly rural farmers will shoot you for "gathering" as you pass through their land. Don't kid yourself, most rural types are better armed than you might think and they do more shooting than the average urbanite. Those rocks along the driveway are range markers.
Katrina is indeed a perfect example. All the chaos and attention was focused on the north exits from town. Yet if you went south you can find over land routes out of the area. The thing is that everyone is thinking north and east. Not south and west. Do this in a city that is land locked and you are going to need 10s of thousands of troops and your own dang satellite to stop motivated and prepared individuals from bugging out. As for it not being possible to go out on foot. I would refer you to almost every modern war. Millions of people have fled wars on foot. Sometimes it is the only choice. It can be done and it has been done in every disaster and war in modern history. But preparing for it can mean the difference between an arduous trek home and a decent into Hades.
The option is yours.
I would put forward that where you are headed to is more important then where you are coming from. You need to not be “Just getting away.†You need to have someplace that you are heading to. Again the people that live out in the sticks or have family that does is better then just getting out of the war zone. And having a stocked retreat or home is the best yet.
