What would I grow?
Old. Healthy and gracefully. Picking off all o' you 'uns that think it's okay to take from me and mine to give to you and yours. Yep, picking 'em off, right up to and including that last day.
Potatoes? Well, just be prepared for the myriad diseases that can wipe them out in a premanent way in any given area.
Imagination's a great thing. All the things we'd do, the mighty men we'd be, all that sort of stuff... truth is: Most men will, at some point in their life, profess to love someone so much that they would willingly lay down their life for them. In reality, few that make the claim will ever be called upon to do so, but vow it anyway, simply because they do not realize that physical death is not the thing required to protect or preserve the life of another. Sometimes it means giving up a destructive lifestyle or habit, sometimes it means concealing the love for that person and walking away before ever beginning a relationship, leaving them to live a richer and happier life without themselves being in their loved one's life. And yes, every once in a great while it may require that we die in order to save the life of another but it is so rare as to be an unreasonable proposition. And that, perhaps, may be the very reason that so many profess a willingness to do something that will most likely never be demanded of them. The simpler sacrifices, though - well that would actually require a degree of character and commitment, wouldn't it? And so it is that most will never do those "lesser" things for loved ones. Or do for society, in a broader sense, those things that would PREVENT
the "SHTF" in the first place. We no longer have a society that understands the meaning of "Civic Duty," let alone one that likely ever heard the phrase. It hasn't been taught in schools since -- what, the sixties? Fifties? Wow... ditto for "sacrifice." Anyways... Yeah, we can talk about TEOTWAWKI all day, all night, and some actually do just that, but in the end? ...it's all just talk. Just as battle plans become meaningless after the first shot is fired, most if not all of this will perish from our minds long before WE perish.
Anyhow... I admit it's got a lot of attraction and I do a LOT more thinking about it than most folks I know. I just got a little carried away.
Think about perennials -- fruit trees where appropriate, grapes, etc., since they get planted once, and even though they don't produce for the first few years or so, they'll be producing for a LONG time after that.
Another thing I rarely see in these types of discussions is the nomadic aspects of life after the SHTF. Most would find it a better option than staking out a place and defending it all the time. Moving target, y'know? Besides, for those of you that would be considering becoming thugs - I mean predatory lenders - or whatever - nomads have a greater chance of survival because YOU know where the OTHER guys are staking claims and planting crops JUST FOR YOU to come and pillage and plunder, etc. So for me? A pirate's life indeed.
