There are very few places CONUS where you will be able to hide for long. Once you're found, you can try to defend yourself with that tiny group, or do it with a much larger one.
That small group means that everyone has a job they have to be doing constantly, which means fatigue, and deprivation if they have to stop for any period of time.
My group spent a huge amount of time at the BOL, this past year. Minimum for anyone was 2 months, some were there for the entire year. Outside of internet signal, phone service, and a habdful of luxury items (candy for the kids, mass-produced booze, etc), EVERYTHING consumed was produced on our property. Our stores weren't even touched.
The closest town of any size to us is over 5 miles away, the closest major road is the same distance. We've spent over 20 years building a 100% self-sufficient community, and have tested our sustainability numerous times. I promise you, we aren't the only group who can say that. I can also promise you, there are groups larger than ours, who are even better at it than we are.
