Excellent points Dan!
Here are some things that I have considered when it comes to preparing for a situation;
If your primary castle is destroyed or damaged beyond living in then evacuation is essential, but it is imperative to have some place to go. Without a suitable destination in mind you become a refugee and within a very short time you'll be dependent on on the government for assistance.
If you plan on heading "for the hills and living off the land" you will probably have to crowd in with all the other people that beat you to the location you had picked out.
There has even been confirmed stories of those that have property back in the woods have shown up for a peaceful weekend and found people had taken up residence in their thought ot be secret mountain retreat. And this without even a situation in progress.
I rather like GHB over BOG. It is my opinion that in the event of a situation I do not just want to survive, I want to maintain life in the manner I am accustomed to. I can better do this in an abode with which I am familiar.
As I stated earlier there may be sometime when "bugging out" is the only option and I have two separate places to go. Other than being prepared to "bug out" to one of those locations I have found my money and energy is better spent on "fortifying" my primary residence with food stocks, generator and other supplies.
I have had my share of C-Rations and MRE's, ya'll can have as much of my share as you want. I am on my second food saver vacuum sealer, having worn the first one out.
I could go on but I think we all understand the main emphasis is preparation.
