Have you guys seen this webpage? I've had it on my links for awhile, but i sort of forgot it was there.
I really like it because so often I hear about what folks will do when they someday reach the country... and here these folks are doing so much in their small city lot! Now granted, they do have a longer growing season than most of us, but still... they grow more food on their lot than I do on my 20 + acres!
No matter what you think of how or why this folks are doing this... I think you'll find WHAT they are doing inspiring.
Makes me want to get out and play in the dirt!
