Save money - plant a garden

Can we garden our way out of this hole? Just a few years ago, the road to riches was clear. We could all sit on our porches drinking mint juleps while our houses appreciated 30% a year. Now, our houses are falling in value by 30% a year. Forget about them. The real money maker, it turns out, was always our backyard. By planting a vegetable garden, we can slash our food bill while eating healthier.
