I couldn't have said it better myself.
Farming in the City
I spent most of this past weekend moving compost around the farm. I really enjoyed it and I am even more excited about the coming growing season. Even though this part was mostly just hard labor it was good food for the soul. Now I have rich, black mounds of new compost adorning my raised beds and new flower beds in several spots around the yard. I split a 7 yard load with 2 of my neighbors, which made it really economical.
