bug out or bug in - all depends on three questions
1) do you have a SAFER place to go than where you are at now
2) can you reasonably get there (travel, supplies, protection)
3) can the new location sustain you better than your current location.
Answer no to any one of those three questions and bug in becomes much more of a viable option. If the answer is no to all three, then bug in is the only option.
In general, city people who are planning ahead, will have a place out in the country that they can bug out to with at least 1 hrs notice.
I don’t have a safer place to go. National Parks are a definite NO, stupid. Our house is logical. I’m rural, not city. If I was city, this is the place I’d bug out to. City can get here in about 45 minutes. We have the supplies and room. But, we only let our closest people know where we are. And those people are prepping. They get it.
