If I were to camp, hecks' Civil War island fort would be ideal. If a military-grade bunker was unavailable, I would pick a hilltop farm in Iowa, Minnesota, Nebraska, or some other heartland state. Build a settlement around the farm on the steepest hilltop I can find, drill for water, and build pillboxes, machine gun nests, and other subterranean fortifications along the perimeter. I would *not* go with a full chain-link fence. Instead, I would use concertina wire because it's better against human opponents. There would be a designated, well-rehearsed "bug-out" plan in place with fully stocked getaway vehicles manned and ready to go at all times. Multiple heavily fortified, well-stocked nearby bug-out fallback positions would be prepared. As with my "Plan A", there would be a minimum of two lookouts on duty at all times.
