Interesting. Tell us more! What do you mean?
In my case, I have the land, but it is hard work without gas/deisel. Without a tractor and power tools, I mean.
I had a beautiful patch of savoy cabages; simply awesome, big, leafy, wonderful plants heading up nicely and then the caterpilars came. I now have swiss cheese cabbage filled with dead caterpillars and caterpillar crap! You see, I used BT on the plants some time ago, it took only a day or two for the caterpillars to hatch and take off eating, then a day or two later they all died in mass. What a mess!
If my family was relying on me to put food on the table, it wouldn't be with cabbage.
Anyway, corn is up and looks nice. Happy to see that, what with all the rain we had over the winter. Still, the weather sure has dried up lately (looks nervously at cloudless sky and drying soil....).
Never mind the work involved with taking care of a garden that big, sans power tools. Heck, it's hard work WITH power tools.
But, like I said, lots of people like to sit around and fantasize about What Might Happen If It All Hits The Fan. Me, I prefer my life with modern comforts, thank you very much.
