I was recently talking to a few of my buddies about what they would do in a shtf situation... Not zombie... Rather huge natural disaster type
Every one of them said "Grab my bag and head to the mountains"
But the thing is... it's easy to block the mountain roads... or stop up the Eisenhower tunnel... And of course that will happen...
And the biggest problem - the people who already live in the mountains are much better armed and stocked than anything you can carry... and they know the terrain.
...So how does your bug-out plan get around this large problem.
