The family has reached a goal I am striving for. I don't have as large of garden as yet, but I have about an acre of pasture I fun sheep and goats on and have it fenced for pasture rotation. My garden is about 75X75 feet with a greenhouse in the corner next to the chicken/turkey yard. I either compost lawn and shrub clippings or feed them to the sheep and goats. I also direct the rainwater runoff from the rain gutters into storage barrels that I use to water the livestock. So my meat sources are varied, chicken, turkey, pigeon, rabbit, goat and lamb. The of course there's the eggs, 1 of the pastures is also an orchard (18 trees), and I eat several edible "weeds" like mustard, lambsquarter, sorrel, and broad plantain (aka Indian lettuce) leaves.
It is a lifestyle many will revert to as time goes on and this recession turns into a full grown depression, and jobs become even harder to get or keep.
