I really respect what they are doing, and look forward to reproducing some aspects of it.
I also find that as I contemplate how I would go about doing this (if I actually do decide to attempt it at some point), my reference points are not in the here and now; they are elsewhere in time and place. My father's mother, B., had a huge vegetable garden. It would have been a truck garden, except she didn't (as far as I know) ever sell any of it (I might not have known if she did). I remember being sent out to the garden with some number of my sisters and a colander to pick carrots and peas and lettuce and radishes and potatoes and so forth for dinner. I remember spending hours (not kicking) with buckets of green beans, destringing them in preparation for canning. On winter visits, she'd sometimes sent Harry out to go get canned peaches or cherries or whatever (that she had put up) to make a pie for dessert. My grandfather, S., had goats. The responsbility for the chickens seemed to be shared. They were really quite surprisingly poor (they had a party line. In the 80s. For those of you not familiar with this concept: http://en.wikipedia.org/wiki/Party_line_(telephony)).
Prior to moving back to Seattle and then returning with a toddler, I had been starting to garden, and started thinking about permaculture. Ha! Maybe in another five years. Altho R. does consistently manage to get something out of the orchard and/or backyard. This last year it was a few tomato plants and some basil, the blueberry bushes and a few apples suitable mostly for cooking.
R. is not down with the canning, and I don't really blame him.
Hence the freezer. But I do wonder, and think about B. a lot right now. And sometimes I think about calling my mother's cousin I., up in Olds. She has a freezer, too -- also quite poor, and the food was always good there.
