I've been reading this thread with interest, and noted many great comments. For us, we'll close the gate when a major event occurs. For instance, when the Chinese virus initially kicked off, we closed the gate and didn't leave the homestead for nearly a month, and monitored the situation. What's a major event? Anything that is a major disruption for society, i.e., financial collapse, war (nuclear or civil), internet collapse, grid collapse, etc.
As a few forum members know, we purchased a parcel of land elsewhere on the Cumberland Plateau. It's just land, but it has given us the opportunity to design and build a homestead/redoubt from scratch. I'll discuss our progress on the project in a separate posting. We feel like there's an urgency to get as much done prior to the elections, as possible. Carrying capacity was a major factor in purchasing a larger parcel of land than where we currently live. Remoteness is a factor too, as the new property is on a gravel road that typically sees maybe 20 cars per day, if that much. We're at that awkward stage, where not all of our preps are at the new site, yet it is definitely a more survivable location for the long term. If the SHTF tomorrow, we would convoy to the new parcel and settle in. True survival is a mindset, not stuff. It's nice to have food for a year, but the knowledge of how to produce food, in the most austere conditions, is more important.
Get those area studies done, and network with your neighbors.
