30 years ago this garden was the only thing that helped my family and millions other people survive when USSR crashed. 600 square meters planted mostly with potatoes provide enough food for family to survive winter and next summer and even sell something. And it's not that hard work, because people usually had their main work for some tiny money and maintained garden before and after work. I think that everyone should own some land to feed himself in the event of economy fallout.
