Our intentions when developing our property was that we wanted to produce all of our needed food. While this is a commendable ideal, it likely won't happen as our lot is just too small. We can definitely come close, but no cigar. We just don't have the space to produce all the items we use like wheat and animal feed. Oil is another issue. We do have olive trees, but olive oil can't be used for everything as it's flavor can sometimes be too strong (example: extra virgin olive oil in mayo is just wrong in my opinion). Then there is also sugar. Sure, we can use honey for a lot of things, but sometimes we just won't have enough honey to cover our needs, esp. during canning season.
