Well sure you'd rather have a place to go. We all would. But how many people do you know that own even 1/2 an acre of land? Maybe a few up in Loveland, but down here in the metro area? Almost zero people do.
Don't think that I'm arguing your point, because I'm not. I totally agree. However, I think the whole point of a BoB is to have something that you keep with you, so in the event that you are either stranded some where, or are left with nothing, then at least you have something to try and get by with until someone takes you in.
I've got a kid and no tent. Realistically, without a vehicle, we're not going anywhere. I've got a place to go to, but unless someone wants to lend me 15 head of cattle, several pigs, goats, chickens, a few acres worth of crops, and about 100 years worth of ranching experience and know how, it's not really going to help too much. I'd have to quit my job and go work on a ranch for a year or something in order to put my "resource" to any use. So, like you said, we'd be staying put for as long as possible. Just try to survive the first few waves of mass deaths.
