"three days further out than a starving person can walk" sounds cool if you're posting fake apocalypse theories on the internet (aka John Titor), but is generally pretty terrible advice. First of all, there are an enormous amount of cars in America and there are roads nearly everywhere. The furthest spot from any road in the lower 48 US states is in Yellowstone, 21.7 miles from the closest road: https://www.bbc.com/news/world-us-canada-42104894 https://www.bbc.com/news/world-us-canada-42104894 Even assuming that there's some kind of enormous EMP that kills all modern cars, there are plenty of pre-80s cars around and around a third of Americans have bikes. You can cover some serious distance on a bike if you're motivated enough (aka by hunger.) There are millions of horses in the USA, not to mention other animals and tools you can use for transportation (canoes etc.) If your bet is to hope that your fellow members of the most adaptable species on Earth won't get to you, you're generally screwed. If you plan to use force (say firearms) to hold back your place, well, that'll attract attention from anyone else (if you look at failed states, you're likely to see roving bands of criminals with more firepower than you.) There are fairly few examples of people who made their apocalypse preparations and actually rode out the local serious disaster in their bunkers, so to me, it's obvious what your best bet is - to simply live in a safe, sane and successful society.
