If you think you can live off the land at the same time several million people are competing with you for scant resources, you're dreaming. My brother, my friends and I took dozens of hunting trips into the mountains of British Columbia over the years. I know what it's like to live out of a pack for days on end, it ain't easy and we had the benefit of resupply at our base camp. The only carnivores we had to deal with were the numerous Grizzly and Black bears, and the rare Mountain Lion. Imagine trying to survive on what you can carry knowing that there will be ambushes waiting for you at every water hole? Bugging out to a remote location with cached supplies is risky and in reality is still "bugging in"....with fewer resources available. I think too many people have a romantic albeit mis-guided notion of "I'm gonna be the next Jeremiah Johnson"! Bugging in won't be easy either...you must be prepared for all-round defense 24/7 with the knowledge that people will snipe at you any time you expose any portion of your body. You will need to "rule the night" and sweep the surrounding area of threats to keep the enemy on the defensive.
Brutal Honesty is Brutal.
Most folks are completely delusional about their ability to survive without assistance. 99% cannot even properly prepare for a basic storm (Snow, Hurricane, etc), with 5 days warning it is coming. 50% of the country though think they are in the 1% that can survive. Ignorance is bliss.
