That's amazing. What does a person do for food, though? If you can't grow your own grains, you'll have to buy them somewhere. Veggies and fruits you could grow if you had the space, but what about bread?
I always try to take on this idea of not buying anything when my husband goes out on tour. I think I've gone 3 days without purchasing anything. It's quite a challenge. He takes off tomorrow for 3 weeks, I"ll see how long I can go. I'll stock up on canned goods and frozen veggies, then cut the ties of consumerism!
